aérer

Aérer is a French verb meaning to introduce air into something, to cause air to circulate, or more generally to ventilate or aerate. It is used for spaces such as rooms, for liquids and foods, and for soils or wines. The sense in everyday speech ranges from refreshing a room by letting in fresh air to lightening a preparation by incorporating air.

Etymology and related terms: the verb is built from the noun air with the standard French -er verb suffix. Its use derives from the basic idea of air passing through or into something. The related noun is aération, referring to the process itself, and aérateur designates a device that performs aeration.

Usage contexts:

- Ventilation of spaces: aérer une pièce or ouvrir les fenêtres pour renouveler l’air.

- Food and liquids: aérer une pâte or aérer le vin to expose it to air and release aromas.

- Soil and horticulture: aérer le sol to loosen compacted earth and improve drainage.

- Metaphorical and personal care: s’aérer l’esprit means to clear or refresh one’s mind.

In each case, the core idea is increasing exposure to air to improve quality, texture, or comfort.

Conjugation and grammar: aérer is a regular -er verb. In the present indicative forms follow the standard pattern: j’aère, tu aères, il aère, nous aér ons, vous aérez, ils aèrent. The past participle is aéré (feminine: aérée; plural: aérés/aérées as appropriate). It can be used with être or avoir depending on the construction and whether a direct object precedes the participle.
