Un homme de parole, un homme de confiance, un homme honnête, loyal

A man of his word = un homme de parole Are you a man of your word ? = Es-tu / Êtes-vous un homme de parole ?

Tiens-tu tes promesses ? => you keep your words (promises) ? Est ce que tu tiens tes promesses? => do you keep your words (promises)?

Means : do you keep your promises?
