the.com/amour

French for love, deployed in English to make an affair sound classier than it is.

means A love affair or romantic passion — often used with a knowing wink to add a bit of flair to romance or scandal.

from Borrowed directly from French 'amour' (love), which descends from Latin 'amor,' from the verb 'amare,' to love. English has been importing the word since the medieval period, often precisely for its foreign shimmer — using 'amour' instead of plain 'love' or 'affair' lets the speaker borrow a little French glamour, the same instinct that gives us 'rendezvous' and 'liaison' for things English words describe just fine, but less seductively.
