These verbs all express the movement of something/somebody from one place to another.

fetch = to go where something or somebody is and bring it/them back

invent/discover
We use both verbs to talk about new things or places.
invent = to design or produce something that has not existed before.
The electric light bulb was invented by T. A. Edison.
discover = to be the first person to become aware that a particular place or thing exists
Columbus discovered America in 1492.
The related nouns are invention and discovery.
The mobile phone is a great invention.
The discovery of fire helped people to survive.
happy/lucky
Both adjectives have a positive meaning. Happy is more personal, coming from the inside, while lucky is more impersonal, coming from the outside.
happy = feeling pleasure; pleased
You don't look happy today. What's the problem?
lucky = having good luck; fortunate (when something good has happened to you by chance)

The related nouns are happiness and luck.
Money doesn't bring you happiness - other people do.
I wish you luck in your new career.
forget/leave
Both verbs mean "to go away from a place without taking something we intended to take". Students sometimes incorrectly say, "I forgot my textbook at home." You can't, however, use forget if you mention the place where you have left something. Compare:
I've forgotten my textbook.
I've left my textbook at home.
Alternatively, you can say, "I've forgotten to bring my textbook from home."
fit/suit/match
These verbs are easily confused when talking about clothes.
fit = to be the right size and shape (clothes/shoes are neither too big nor too small)
This jumper doesn't fit me - the sleeves aren't long enough.
suit = to make you look attractive (clothes/shoes look good on you - their style, colours, etc.)
The hip-hop style suits you best - you look ten years younger.
match = to combine well (clothes/shoes look attractive together - their colours, patterns, materials, etc.)

The phrasal verbs go with and go together have the same meaning.
This jacket doesn't go with this skirt.
This jacket and this skirt don't go together.
alone/lonely
Alone is a more neutral adjective while lonely implies a negative feeling.
alone = without any other people
Uncle Jack lives alone. He has a lot of friends, though, so he doesn't feel lonely.
On one's own and by oneself are less formal phrases used especially in spoken English.
I made this bookshelf on my own. (= without anyone's help)
I'm going on a trip by myself tomorrow. (= with nobody else)
lonely = unhappy because you have nobody to be with

I hope you'll never ever feel lonely. See you.
