What is the difference in meaning or application between "Consequently," and "In Consequence," when placed in the start of a sentence?
Many thanks for your kind attention and probable guidance.
Both are perfectly good, and have exactly the same meaning. It's a matter of fashion. In the early 18th century we said consequently far more than in consequence; then for about 120 years the reverse was true; nowadays we've gone back to consequently again! See Google Ngram Viewer.
And can I extend the similarity of "Consequently," and "In consequence," also to "As a consequence,"? And meanwhile is it acceptable to use both "Consequently," and "In consequence, " in different parts of a 15-25 pages manuscript?
