It's a terrible sentence Ahmed, with several possible meanings, depending upon whether it's supposed to be a complete sentence itself…

…where the writer is suggesting his respondent's question or comment is answered by a phrase starting another paragraph somewhere describing the status of adjectives and pronouns and beginning with the phrase, " 'Being….it modifies….' is being implied." However if that's the case the phrase should have ben enclosed in quotes

….or more likely the "sentence" you give us, Ahmed, isn't a sentence but itself a phrase. With reference to some other unnamed sentence or phrase containing a part of speech that can stand alone whenever the noun it modifies is clearly implied by the context:

"...who at the threat of a storm rushed to the storefront overhanging provision". where the adjective might otherwise modify "retractible awning"

Been a pleasure Ahmed though this single effort hasd so worn me out I'm hoping some of our more patient participants might be of further help

This is a HORRIBLE sentence, but here goes:

"Being an adjective or pronoun that stands alone when the noun it modifies / is being implied . . . but . . .(it) / is not stated."

"but" is a conjunction, joining two parts

Meaning:
It is being implied but it is not stated.
