    Wow. That was very useful and explanation was simple. Thanks. I’m sure I was taught that at school but I forgot!

    Both words have an E. Maybe say Complement with more than one E.

    Very well explained. But how do you pay a complement during e.g. Christmas or new year as people usually say complement or is it compliment of the season? I always use the “e” as I believe it is the correct one.

    No, it’s “pay a compliment” and “compliments of the season.”
