The adverb albeit is used to reduce the force or significance of what has just been said or written.
Synonyms are even though, although, much as or notwithstanding.
The word origins from the 14th century and is a contraction of al be it – al(though) it be (that). A declining use of the word in the 19th century, but then in the 20th century when the “archaic” word really made a comeback and picked up again in use.
He has a very good idea, albeit a strange one.
He was making progress, albeit in rather slow steps.
It was very nice jewellery she possessed, albeit expensive.
