Inflectional morphemes change what a word does in terms of grammar, but does not create a new word. The inflectional morphemes -ing and -ed are added to the base word skip, to indicate the tense of the word. If a word has an inflectional morpheme, it is still the same word, with a few suffixes added.
What lines?. There’s not enough information
1 plus 1 equals 2 thats all i know :)
