How can i identify and use different parts or speech correctly?

Step-by-step explanation:

Understanding parts of speech is essential for determining the correct definition of a word when using the dictionary. 1. ... Nouns can function in different roles within a sentence; for example, a noun can be a subject, ... pronouns introduce a subordinate clause; and demonstrative pronouns identify, point to, or refer to nouns

Pronouns: Words that take the place of a noun or another pronoun (I, you, me, he, she, it, we, who, they).

English has 9 parts of speech:

part of speechfunction or "job"example wordsexample sentences

Verbaction or state(to) be, have, do, like, work, sing, can, mustEnglishClub is a web site. I like EnglishClub.

Nounthing or personpen, dog, work, music, town, London, teacher, JohnThis is my dog. He lives in my house. We live in London.

Adjectivedescribes a noungood, big, red, well, interestingMy dogs are big. I like big dogs.

Determinerlimits or "determines" a nouna/an, the, 2, some, manyI have two dogs and some rabbits.

Adverbdescribes a verb, adjective or adverbquickly, silently, well, badly, very, reallyMy dog eats quickly. When he is very hungry, he eats really quickly.

Pronounreplaces a nounI, you, he, she, someTara is Indian. She is beautiful.

Prepositionlinks a noun to another wordto, at, after, on, butWe went to school on Monday.

Conjunctionjoins clauses or sentences or wordsand, but, whenI like dogs and I like cats. I like cats and dogs. I like dogs but I don't like cats.

Interjectionshort exclamation, sometimes inserted into a sentenceoh!, ouch!, hi!, wellOuch! That hurts! Hi! How are you? Well, I don't know.

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!
