Word formation

when we add 'ing' with a word .does it change it's meaning. for example "help" and "helping"
what is the dffreance beetwen these two words

Any time you add anything to a word you change its meaning. In this case, "To help" still retains its overall semantic meaning, providing assistance, but the contextual meaning changes;

"Help" could be someone asking for help as in, "Help me."

But "Helping" is the present progressive, as in someone is actively assisting someone.

Or, it could be the gerund as in, "Helping people makes me feel good."
