Does amour have an apostrophe in it?

The Word amour has no apostrophe in it but when using it an apostrophe (') is needed with de or le:

Parlez moi d'amour

L'amour toujours...

(Used with beau, beau is changed to bel : bel amour, but this rule is related to beau in front of a masculine Word starting with a vowel: un bel équipage)

BUT

mon amour

un amour de chien

les amours

By the way, amour is masculine when singular and feminine when plural

Un amour troublant

Des amours troublantes
