I just wonder when/how to take away unnecessary parts in a sentence. Let's bring up a few couple of examples:
I. An egg mixture
which iscooked until they arejust set. (src: Omelet, WordNet 2.0)II. Though aged she is, she still runs her small store.
Would someone please explain such rules grammatically because I still do removals intuitively!
Thanks in advance,
I've a tiny clue that you're allowed to delete when dealing with "To Be" verbs.
As 5jj said, it's hard to say how to remove words from already incorrect sentences. With your second example, if the word order were changed, it would have been possible to have "she is" in it.
Elderly though she is, she still runs a small shop.
With that sentence, there are no words which could be omitted and still leave a meaningful sentence. You could omit "still" but it loses meaning.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
