In the following sentence " I meet him on friday" ,:
I meet him on Friday.
we use preposition 'on' before 'friday' 'Friday', but in the following sentence "I met him last friday":
I met him last Friday.
we dontdon't use preposition before 'last friday' "last Friday". theThe word 'friday''Friday' is normally noun but when we add 'last' in front of it , does it become adverb ?
