First, the word you need for the title of your thread is
grammar, not grammer.
Second, precis writing is not
telegraphic style writing.
Quote:A telegraphic style condenses writing by omitting articles, pronouns, conjunctions, and transitions. Engineers often use the telegraphic style for instructions and specifications thinking that it’s more concise. However, telegraphic style writing forces the reader to supply the missing words, which creates the potential for ambiguity or misunderstanding.
While writing a precis, you need:
- conciseness
- clarity
-
completeness
- unity
- coherence.
