First let's talk about some words or phrases for better understanding the topic.
These are:
All of the things are pretty confusing specially if you are in beginner level.
For example: The music was very loud nevertheless it was enjoyable.
Some other common connectors: And, as well as, but, or, yet, nevertheless, however, so that, as long as, while, until, as if, because, when, after, though, before all are connector.
Types of connector
Sub-ordinating conjunction: A subordinating conjunction connects a sentence with another on which it depends for its full meaning.
See examples:
The prominent subordinating conjunctions are after, because, if, that, though, although, till, before, unless.
Co-ordinating conjunctions: Coordinating conjunctions join together clauses of equal importance.
Some examples of coordinating conjunctions are - and, but, or.
Use of 'and'
'And' is used as a conjunction when the words or phrases are of equal importance and both conditions exist.
Other words that can be used in place of and are: moreover, in addition to, along with, plus, as well as, further more
Example:
Use of 'but'
The conjunction 'but' is used to show a contradiction between two phrases. Let's say the first phrase leads you to expect a certain event and the second phrase tells you quite a contradictory outcome. In such an event, but, is used.
Other words like: nevertheless, yet, however, can be used in place of 'but'
Example:
Use of 'Or'
When we need to express a choice between two words or phrases we use 'or'. Here only one of the two conditions exists.
Example:
Co-relative conjunctions: Conjunctions used in pairs are correlative conjunctions.
Either..... or, Neither.....nor, Both.....and, Whether..... or, Not only..... but also
Example:
Compound conjunctions: Compound conjunctions are groups of words that behave like conjunctions. Such as in order that, on condition that, provided that, as soon as etc.
