strengthnesses - I was just wondering whether "strengthnesses" is a fully English word or a sort of uncorrect made up word.

Could you say "(their) weaknesses and strengthnesses"?
  • Weaknesses is correct. There is no "..ness" form for strong, whereas there is for weak.
    Please note that it is INcorrect, not UNcorrect.
    Weaknesses is OK.

    You are looking for a noun.

    Many adjectives form nouns by adding -ness.
    Weak is one of them: weak -> weakness.
    Strong is not: strong -> strongness strong -> strength.
    To add -ness to strength is a silly as adding -ness to weakness -> weaknessness.
