Explanations

DESCRIBING PEOPLE

Questions:

1- How is your mother? He's very well, thank you.     (health)
2- What does your mother look like? She's short but very beautiful.    (appearance)
3- What's your mother like? She's very nice and friendly.    (personality)
4- What does your mother like? She likes pizza and coffee.

PHYSICAL DESCRIPTION

- She is tall / short, beautiful / ugly, fat / thin, plump / slim
(we use "handsome" for men, and "beautiful" for the rest)

We can also make descriptions using the preposition WITH or the verb HAVE GOT (we can also use HAVE, but in British English it is better to use HAVE GOT for physical description).

- She's got long fair hair and blue eyes
- He's a fat man with a big head

-ISH When a person is not short, but not very tall, we can say:
- he's a bit tall
- he's tallish
- he's more or less tall
- he's tall, but not exactly
Grading extremely short, very short, short, quite short, shortish, a bit short, a bit tall, tallish, quite tall, tall, very tall, extremely tall.
quite = rather = -ish = pretty
Notice the difference:
- She's very pretty (pretty = beautiful)
- She's pretty tall (pretty = quite)

Clothes and complements For clothes and complements we can use WITH or TO WEAR, but with clothes we usually prefer IN or TO WEAR:
- There is a boy in green trousers
- He's wearing jeans and a white shirt
- I can see a man with an old hat wearing glasses
- She's wearing a long skirt and black shoes
HAVE (GOT) We can use this verb to describe clothes and complements, but it is more ambiguous:
- He's got glasses (we don't know where the glasses are, maybe on his face, maybe at home, maybe inside a box)
- He's wearing glasses (the glasses are on his face)

SOME OTHER QUESTIONS:
- How tall are you? I'm 1.80 / I'm 1 metre 80 centimetres / I'm 1 metre 80
We often use the word TALL at the end: I'm 1 m. 80 cms tall
(English speaking countries usually use "foot" and "inches" instead of "metres" and "centimetres" and "pounds" instead of "kilos") : I'm 5 feet, 4 inches tall.
- How much do you weigh? I weigh 75 kilos / He weighs 175 pounds
- What hair colour are you? I'm dark / brown / blond = fair / grey, white

PERSONALITY

- He's a nice person but sometimes he can be very unfriendly, especially when he is angry.
- She's very patient, but yesterday she was very nervous and rude
- I like her, she's nice and beautiful and she's got a wonderful smile

As you can see, the grammar here is quite simple, the most important thing is to learn vocabulary for description.
