Every noun in a real sentence is usually part of a noun phrase. You rarely say just "dog". You say "the dog", "a big brown dog", "the dog that bit me". All of these are noun phrases. The noun "dog" is the head. Everything else supports it.
Noun phrases can function as the subject, object, or complement of a sentence:
Object: She designed a powerful algorithm.
Complement: He became the lead developer.
In apposition: My teacher, a brilliant woman, inspired me.
In O Level and IGCSE exams you may be asked to identify or expand noun phrases. The longer and more precise a noun phrase, the more information it carries without needing extra sentences.
The tricky part is that a gerund looks exactly like a present participle. The difference is the role it plays. If the -ing word acts as a noun in the sentence, it is a gerund. If it describes a noun or forms a continuous tense, it is a participle.
Participle (adjective): The swimming fish moved fast. (describes fish)
Participle (verb): She was swimming when I called. (continuous tense)
Quick test: Replace the -ing word with a regular noun. If it still makes sense, it is a gerund.
Swimming is my favourite sport. → Chess is my favourite sport. ✓ Gerund!
