Aside from frequency in Books, are there any differences in terms of meaning, usage or register/connotation between
vicinity [plural vicinities] [Merriam-Webster]: 1: a surrounding area or district: neighborhood
2: neighborhood sense 3b {an approximate amount, extent, or degree
- cost in the neighborhood of $100} [qv]
3: the quality or state of being near: proximity
and
vicinage [Merriam-Webster]:
a neighboring or surrounding district: vicinity
Books seem to contain less and less of these two words; is that correlated to the rise in the usage of neighborhood? Is the ngram showing anything meaningful here?
