The Spanish family word for a male child is “hijo”—spelled H-I-J-O.
You’ll see “son” all over English, and it feels straightforward until you try to write it in Spanish. Then the meaning matters. English uses one word for a family relationship, a form of “to be,” and even part of words tied to audio. Spanish splits those ideas into different spellings. Once you know which meaning you want, spelling it is easy.
This article gives you the spelling you’re likely after, then shows the other common meanings people mix up with it. You’ll get letter-by-letter help, clean examples you can copy, and a few practice drills so it sticks.
How to Spell ‘Son’ in Spanish
If you mean son as in a male child, the Spanish word is hijo. It has four letters and no accent mark. The first letter, h, is silent in modern Spanish, so you write it but you don’t say it.
Letter-By-Letter Spelling
- H – silent letter at the start
- I – vowel sound like “ee”
- J – a throaty sound, close to an English “h” in many accents
- O – vowel sound like “oh”
If you’re spelling it out loud, you can say, “H, I, J, O.” If you’re reading it, it often comes out as “EE-ho,” with the breathy sound coming from the J, not from the H.
What About Accent Marks
Hijo does not take an accent mark. You might see accents in Spanish family words like mamá or papá, so it’s fair to wonder. In this case, the spelling stays plain: hijo.
What “Hijo” Means In Real Life
Hijo is used for “son” in the family sense: someone’s male child. It can point to a small kid, a teen, or a grown adult. Spanish does not change the core spelling based on age.
You’ll often see it with an article or a possessive. Here are patterns that show up a lot:
- El hijo – the son
- Mi hijo – my son
- Su hijo – his son, her son, or their son (context clears it up)
- Nuestro hijo – our son
Spanish uses context more than apostrophes. English writes “my son’s backpack.” Spanish often uses de: la mochila de mi hijo. Same idea, different structure.
Pronouncing “Hijo” Without Getting Stuck
Spelling is one thing. Saying it can feel odd at first because English doesn’t use the same J sound. Here’s a simple way to keep it steady: start with a clear “ee” sound, then add a breathy “h” sound, then finish with “oh.”
Two small tips help a lot:
- Don’t voice the H. The H is silent, so the sound comes from the J.
- Keep the vowels clean. Spanish vowels stay stable. The I stays “ee,” and the O stays “oh.”
If you’ve heard Spanish from different places, you may notice the J varies. Some speakers use a softer breath. Others use a rougher sound. The spelling stays the same either way.
Pick The Meaning Before You Write The Word
Before you reach for a Spanish spelling, stop for a second and ask what “son” is doing in your sentence. Are you naming a person in a family? Are you linking a plural subject to a description? Or are you talking about audio?
Spanish uses different words for each idea, so one English word can’t map to one Spanish spelling. Once you sort the meaning, the spelling choice stops feeling like a guess.
Here’s a simple swap test you can do while you write. Replace the word with “my child.” If the sentence still works, you’re in the family meaning. Replace it with “they are.” If that works, you’re in the verb meaning. Replace it with “noise” or “sound.” If that works, you’re in the audio meaning.
- Family noun: you can swap it with a name, like “my son Daniel.” In Spanish, that points to hijo.
- Verb form: it follows a plural subject and means “they are.” In Spanish, that is son.
- Audio word: it sits near words like “noise,” “sound,” or “ring.” In Spanish, you’ll usually want sonido or a form of sonar.
Now you’re set up to spell the family word cleanly, then sort the other meanings when they show up.
| English Idea | Spanish Spelling | How It’s Used |
|---|---|---|
| My son | Mi hijo | Possessive + family word |
| The son | El hijo | Article + noun |
| Her son | Su hijo | Context tells whose |
| Our son | Nuestro hijo | Possessive agrees with “we” |
| Sons | Hijos | Plural form of hijo |
| Daughter and son | Hija e hijo | Pairing feminine and masculine |
| Children (mixed group) | Hijos | Often used for sons or kids as a group |
| Only daughters | Hijas | Feminine plural |
| That’s my son | Ese es mi hijo | Pointing someone out |
| My son’s book | El libro de mi hijo | Uses de instead of apostrophe |
Spelling “Son” In Spanish Across Meanings
Now for the part that trips people up: English “son” can point to other meanings that are not the family word. If you pick the wrong Spanish spelling, the sentence can read like a different idea. No big deal, but it can feel awkward.
When “Son” Means “They Are”
If you mean son as “they are,” Spanish often uses the exact same three-letter form: son. This is the ellos/ellas/ustedes form of ser (to be). It’s not a noun. It’s a verb.
Here are a few clean sentence patterns:
- Ellos son altos. (They are tall.)
- Mis amigos son estudiantes. (My friends are students.)
- Ustedes son de México. (You all are from Mexico.)
Notice the clue words: ellos, ellas, ustedes, or a plural subject like mis amigos. If you see a plural subject, there’s a strong chance son is the verb, not the family noun.
When “Son” Points To Sound
English uses “son” inside words tied to audio, like “sonic.” Spanish usually uses sonido for “sound.” You may also see sonar (“to sound”) in phrases about how something sounds.
These are common spellings you can lean on:
- Sonido – sound (noun)
- Sonar – to sound (verb)
- Suena – it sounds
So, if your English sentence is about audio, odds are high that hijo is not what you want. A “son” at a concert is not a child; it’s a sound. Spanish will steer you toward sonido.
Forms And Spellings You’ll See Around “Hijo”
Once you’ve got hijo down, the next thing is learning the family forms that spin off from it. These show up in school Spanish, travel Spanish, and daily chat. The spelling stays predictable once you know the pattern.
Plural And Gender Forms
- Hijo – son
- Hija – daughter
- Hijos – sons, or children in a mixed group
- Hijas – daughters
That last point matters: hijos can mean “sons,” yet it can also mean “children” when the group includes at least one boy. If the group is only girls, use hijas.
Smaller, Warmer Forms
You may hear diminutives in conversation. They signal closeness or affection. The spelling changes by adding a small ending:
- Hijito – “little son” or “dear son”
- Hijita – “little daughter” or “dear daughter”
These are more common in speech than in formal writing, yet it’s useful to recognize them so you don’t mistake them for a different word.
Spelling Details That Cause Mix-Ups
Most spelling errors with hijo come from English habits. English speakers want the H to make a sound, or they want to drop it to match what they hear. Spanish doesn’t work that way here. You write the silent H each time.
Another frequent snag is the letter J. In English, J is often a “juh” sound. In Spanish, J is a breathy sound. That’s why hijo does not sound like “hijo” would in English phonics. The letters still stay put: H-I-J-O.
A third snag is possessives. If you try to force an English-style apostrophe into Spanish, the sentence starts to look off. Spanish uses de or a possessive adjective instead.
| Common Slip | What It Can Mean | Better Spanish Choice |
|---|---|---|
| ijo | Misspelling (dropped silent H) | hijo |
| hio | Misspelling (lost the J) | hijo |
| hijo’s | English apostrophe pattern | de mi hijo / del hijo |
| son (family sense) | Reads as “they are” | hijo |
| hijo (verb sense) | Reads as “son” (child) | son (they are) |
| son (audio sense) | Not clear as “sound” | sonido |
| hijo with an accent | Unneeded mark | hijo (no accent) |
| mi hijos | Mismatch (singular + plural) | mis hijos / mi hijo |
| su hijo unclear | Whose son is it | su hijo + name or context |
Practice Drills To Lock In The Spelling
Reading rules helps, yet spelling sticks faster when you write it a few times. Here are short drills you can do on paper or in a notes app. Give yourself two passes: one slow pass, one normal-speed pass.
Drill 1: Fill In The Missing Letters
- Mi ____o se llama Daniel.
- Ella tiene dos ____os.
- Ellos ____ profesores.
- El ____ido es alto.
Drill 2: Pick The Right Word
Choose hijo, son, or sonido for each line:
- Mis amigos ____ muy simpáticos.
- Ese es mi ____.
- El ____ de la música es bajo.
- Mis ____ estudian en casa.
Answers
- Mi hijo se llama Daniel.
- Ella tiene dos hijos.
- Ellos son profesores.
- El sonido es alto.
- Mis amigos son muy simpáticos.
- Ese es mi hijo.
- El sonido de la música es bajo.
- Mis hijos estudian en casa.
A Clean Way To Check Yourself While Writing
If you’re mid-sentence and you’re not sure which spelling you need, use this small check:
- If it’s a person in a family, write hijo or hijos.
- If it pairs with a plural subject and means “they are,” write son.
- If it’s about audio, write sonido or use sonar/suena.
Next, glance at the words next to it. If you see el, mi, su, or nuestro, you’re working with a noun. If you see ellos or ellas right before it and a description right after, you’re working with the verb.
Then decide if you need a different family form. A male child is hijo. A female child is hija. More than one child becomes hijos or hijas. In a mixed group, hijos is the standard plural in most writing.
One more check: if you can swap the word with “child,” it’s a noun; if you can swap it with “are,” it’s the verb there instead.
That’s it. Once you tag the meaning, the spelling follows on its own.
