Nouns change their form for only two grammatical reasons:
Countable nouns have a plural form. This is usually formed by adding –s, of course, but there are some irregular forms.
The possessive form of a noun is created by adding –’s (Henry’s cat) or just an apostrophe (all our students’ results).
Slide 18
Some nouns retain plural endings from Old English:
Men, geese, mice, oxen, feet, teeth, knives.
Loan words from Latin, Greek, French and Italian sometimes keep their native ending:
Media, bacteria, formulae, larvae, criteria, phenomena, gateaux.
Graffiti, an Italian plural, is now an uncountable noun in English.
Slide 19
When we see a noun as performing a role in a sentence, we think of it as a noun phrase.
A noun phrase may function as the subject or object of a clause.
A noun phrase may consist of a single word (a noun or pronoun) or a group of words.
The most important noun in a noun phrase is called the headword.

A young (man) in a suit was admiring the (view) from the window.
Concentrated sulphuric (acid) must be handled carefully.

Slide 21
The headword of a noun phrase may be pre-modified by determiners, adjectives or other nouns.
For example, a large, dinner (plate).
It may be post-modified by a prepositional phrase.
This is simply a noun phrase with a preposition at the beginning.
For example, a (painting) by Rembrandt.
