Do suggest the must read critical terms that needs to be referred from penguins critical text dictionary

not Literary terms . critical terms I need

there are too many for many . can u cite critical terms if possible

M. h. abrhams is also good, but a bit sketchy

it is a long list. but you can read through as much as possible. you can also consult Cuddon for literary terms and Tom Bottimore for Marxist terminologies.
