especially

Especially and also, unlike German besonders and auch, cannot be used to modify a noun at the beginning of a sentence.

*Especially men have this problem.
Men, especially, have this problem.

*Also men have this problem.
Men also have this problem.

With also, initial position is possible if followed by a pause (and comma), in which case it is equivalent to furthermore:

Also, most women would agree.
Furthermore, most women would agree.
