A phrasal verb is made of two pieces: a normal verb, and a preposition.
Its meaning is completely different from the meaning of the normal verb.
Example :
"look" is a normal verb and means "watch " or "see" ("তাকানো" in Bengali).
But "look for" is a phrasal verb and means "search" ("খোঁজা" in Bengali ).
"for" is a preposition, and when we add it to "look", it changes its meaning completely.
A sentence with "look" meaning " তাকানো ":
Don't look now.
(এখন তাকিও না।)
A sentence with "look for" meaning " খোঁজা ":
I'm looking for the keys.
আমি চাবিগুলো খুঁজছি।
