How do I construct the French conditional tense for regular verbs?

To make the conditional tense in French you need to take the infinitive form of the verb, the form found in the dictionary, and add an ending onto it. These endings are:

Je (I) - ais

Tu (You) - ais

Il/Elle/On (He/she/we) - ait

Nous (We) - ions

Vous (You) - iez

Ils/Elles (They) - aient

Then you need to add the correct ending to the infinitive, the ending which matches the subject/ person who is doing the verb. This means that to make the conditional tense you need: Subject + Infinitive + Ending

Example

Je chanterais - I would sing       Je (Subject) + Chanter (Infinitive) + ais (Matching ending)

Tu mangerais - I would eat        Tu (Subject) + Manger (Infinitive) + ais (Matching ending)

Nous Danserions - We would dance       Nous (Subject) + Danser (Infinitive) + ions (Matching ending)
