Cultural Tip
The word 'infos' is everyday slang for 'informations' and is perfectly natural in spoken French and informal writing. However, it can sound too casual in business letters, official documents, or when speaking to strangers. Likewise, the contraction 'T'as' signals familiarity; switch to 'Vous avez' for politeness or when you’re not on a first‑name basis.
