Happy New Year to all.
I have been wondering if "seasons greetings" without an apostrophe instead of "season's greeting" with an apostrophe is becoming common.
I have often seen the title of the book, street signs, sings in the shop window without an apostrophe.
I found several books in Amazon without an apostrophe.
One of them is a "Seasons Greetings: poems about seasonal depression.
The author writes as follows in the description of the book, using "Season's".
Season's Greetings is a collection of poetry bringing to life the highs and lows of seasonal affective disorder (or more commonly known as, Seasonal Depression).
"Seasons Greetings" is not grammatically correct , is it?
