The four jobs of à

a point in space · a point in time · a recipient · a defining traitA1

In one line

à is French for at. At the corner · at eight o'clock — one spot, whether on a map or on a clock. And the same à, pointed at a person, means something reaches them.

#JobWhat it saysExamplePronunciation
1a point in spacewhere — destination or resting place alikeJe vais à Paris./ʒə vɛ.z‿a pa.ʁi/

3a recipientwho something reachesJe parle à Marie./ʒə paʁl a ma.ʁi/
4a defining traitwhat a thing is for, or what marks it outune machine à laver/yn ma.ʃi.n‿a la.ve/

All four do the same thing: they put a finger on one spot. The rest is detail.

What "a point" means, in the plainest terms

English has the same word, and you use it every day: at.

EnglishFrenchPronunciation
at the cornerau coin de la rue/o kwɛ̃ də la ʁy/
at eight o'clockà huit heures/a ɥi.t‿œʁ/
at workau travail/o tʁa.vaj/

At means one spot you could put a finger on. A map and a clock face are the same kind of thing: a surface with marked positions. à says here.

And that explains where à does not go: you never say "at tomorrow" either, because tomorrow is not a spot — it is a whole day. So demain stands bare in French too:

Je pars à huit heures et je reviens demain.

Your English instinct is right here — French simply makes the word obligatory where English sometimes drops it.

1) A point in space — where English makes you choose and French does not

English uses to for going and at for being there. French uses à for both:

EnglishFrenchPreposition
I'm going to ParisJe vais à Paris. /ʒə vɛ.z‿a pa.ʁi/à /a/
I'm at ParisJe suis à Paris. /ʒə sɥi a pa.ʁi/the same à /a/
I'm going to schoolJe vais à l'école. /ʒə vɛ.z‿a le.kɔl/à /a/
I'm at schoolJe suis à l'école. /ʒə sɥi a le.kɔl/the same à /a/

Movement or stillness is decided by the VERB, not the preposition. aller moves, être does not — à is identical in both.

Countries are the exception: à Paris ✅ but au Canada · en France — the rule is in lieux-a-en-au.

2) A point in time

ExampleMeaningPronunciation
à midiat noon/a mi.di/
à huit heuresat eight o'clock/a ɥi.t‿œʁ/
à demainsee you tomorrow — an everyday goodbye/a də.mɛ̃/
au printempsin spring — à + le printemps/o pʁɛ̃.tɑ̃/
de neuf heures à cinq heuresfrom nine to five/də nœ.v‿œʁz a sɛ̃k œʁ/

à is a moment, not a stretch. For a stretch you have en, pendant, dans — in prepositions-temps.

3) A recipient — and this is exactly where English misleads you

When something reaches a person, that person arrives with à:

FrenchMeaningPronunciation
parler à quelqu'unto speak to someone/paʁ.le a kɛl.kœ̃/
donner à quelqu'unto give to someone/dɔ.ne a kɛl.kœ̃/
téléphoner à quelqu'unto call someone/te.le.fo.ne a kɛl.kœ̃/
répondre à quelqu'unto answer someone/ʁe.pɔ̃dʁ a kɛl.kœ̃/
penser à quelque choseto think about something/pɑ̃.se a kɛl.kə ʃɔz/
demander à quelqu'unto ask someone/də.mɑ̃.de a kɛl.kœ̃/

English matches French on almost none of them:

Pronunciation
parler àEnglish also says "to" ✅ the one that lines up/paʁ.le a/
penser àEnglish says "think about" — mismatched/pɑ̃.se a/
téléphoner àEnglish says "call somebody", no preposition — mismatched/te.le.fo.ne a/
répondre àEnglish says "answer somebody", no preposition — mismatched/ʁe.pɔ̃dʁ a/
demander àEnglish says "ask somebody", no preposition — mismatched/də.mɑ̃.de a/

So do not reach for the English preposition. Learn each verb together with the preposition it takes — the list is in verbe-prepositions, and the pronoun that replaces it is in pronoms-coi.

And a related use: ownership after être:

Pronunciation
C'est à moi.It's mine/sɛ.t‿a mwa/
Ce livre est à Marie.This book is Marie's/sə livʁ ɛ.t‿a ma.ʁi/

4) A defining trait — what a thing is for, or what marks it out

ExampleMeaningWhat it tells youPronunciation
une machine à lavera washing machinewhat it is for/yn ma.ʃi.n‿a la.ve/
un verre à vina wine glasswhat it is for/œ̃ vɛʁ a vɛ̃/
une brosse à dentsa toothbrushwhat it is for/yn bʁɔs a dɑ̃/
une fille aux yeux bleusa blue-eyed girlwhat marks her out/yn fij o.z‿jø blø/
un menu à quinze eurosa fifteen-euro menuits price/œ̃ mə.ny a kɛ̃.z‿ø.ʁo/
à pied
à vélo
on foot · by bikethe manner/a pje/ · /a ve.lo/

The classic trap — à is purpose, de is contents:

un verre à vin = a glass made for wine, possibly empty un verre de vin = a glass with wine in it

And a fifth job: à + infinitive

Here à means "for", or is simply the joint between two verbs:

PatternExampleMeaning
verb + à /a/ + infinitivecommencer à parler /kɔ.mɑ̃.se a paʁ.le/to start speaking
apprendre à nager /a.pʁɑ̃dʁ a na.ʒe/to learn to swim
réussir à finir /ʁe.y.siʁ a fi.niʁ/to manage to finish
noun + à /a/ + infinitivequelque chose à faire /kɛl.kə ʃɔ.z‿a fɛʁ/something to do
une chambre à louer /yn ʃɑ̃bʁ a lwe/a room to let
adjective + à /a/ + infinitivefacile à comprendre /fa.sil a kɔ̃.pʁɑ̃dʁ/easy to understand

Exceptions

ExceptionWhat happens
à /a/ fuses with le /lə//les /le/au /o/ and aux /o/ — compulsory, no exceptions. Detail in au-du-des
Cities take à /a/, countries do notà Toronto /a to.ʁɔ̃.to/ but au Canada /o ka.na.da/
en France /ɑ̃ fʁɑ̃s/ — in lieux-a-en-au /ljø.za.ɑ̃.no/
Vehicles: à /a/ or en /ɑ̃/?If you sit on it, à /a/ (à pied /a pje/
à vélo /a ve.lo/
à cheval /a ʃə.val/); if you sit in it, en /ɑ̃/ (en voiture /ɑ̃ vwa.tyʁ/
en bus /ɑ̃ bys/
en avion /ɑ̃.n‿a.vjɔ̃/)
à /a/ never precedes a direct-object pronounJe le vois. /ʒə lə vwa/ not Je vois à lui /ʒə vwa.z‿a lɥi/ — only the indirect object takes à /a/
à /a/ has the accent, a /a/ does notà /a/ is the preposition, a /a/ is avoir /a.vwaʁ/ in the third person: Il a un livre. /i.l‿a œ̃ livʁ/ against Il va à Paris. /il va a pa.ʁi/ They sound identical — in homophones /o.mo.fon/

Il à un livre.Il a un livre.That a is the verb; it takes no accent
J'ai commencé parler.J'ai commencé à parler.commencer links to its infinitive with à

Why one word does so much

A Latin case that collapsed and handed its work to `à`

Latin had a separate noun case for the recipient, the dative — no preposition was needed, the noun itself changed shape:

LatinMeaningPronunciation
Mariaeto Maria/ma.ʁje/
MariamMaria (direct object)/ma.ʁjam/

In French those cases disappeared and the language had to do their work with prepositions instead. à took the job.

And because à comes from Latin ad, meaning "towards", that same picture — a point something arrives at — survives in every one of its uses:

JobWhat the point is
spacea point on the map
timea point on the clock
recipientthe person something reaches
traitthe purpose a thing was built towards

So these four jobs are not four rules — they are one rule seen in four places.

And de is its mirror image: from Latin de, meaning "from", it absorbed the work of the genitive and ablative cases. One towards, one away. The contrast is in a-ou-de.
