conjunction adverbs

[binsadan]

Hello,

I want to ask please about some words of conjunction adverbs, for example:
(consequently, furthermore, moreover)

(also , likewise)

Can we use these words interchangeably ???
what is the most used vocabulary ??
thank you so much

I think we need to be a little careful about terminology here: although grammarians are not 100% uniform in their use of terminology, the 'linking' words that you cite are generally referred to as adverbial conjuncts, rather than as 'conjunction adverbs'. (This latter would, in in any case, be something of a contradiction in terms, since the labels 'conjunction' and 'adverb' denote mutually exclusive basic form-classes.)

Just to complicate things further, some more traditional grammarians, e.g. Fowler, employ the term 'conjunctive adverb' to denote an interrogative adverb used as a clause-connector, such as 'when' in

He asked me when I would be leaving.

Regarding adverbial conjuncts (so, therefore, yet, etc.) standing in mid-sentence position: since they are, strictly speaking, members of the form-class adverb rather than the form-class conjunction, purists will tend to insist on their always being prefixed by a true coordinating conjunction (and, but, etc.), thus amending e.g. popularly acceptable

He's away today, so they've cancelled the meeting.

to

He's away today, and so they've cancelled the meeting.

Furthermore and moreover both mean in addition and are usually synonymous.

Consequently is different, meaning as a result of what has been said before.

As for also/likewise, you will find this link interesting:
