Ordinary any more [usually with negative or in questions]
- to any further extent; any longer:
she refused to listen any more
Positive any more is the use of the adverb any more in an affirmative context.
A servant being instructed how to act, will answer 'I will do it any more'
meaning: from now on
Pantyhose are so expensive anymore that I just try to get a good suntan and forget about it.
meaning: nowadays
Can you always substitute it in place of either of these? Does it have any other uses? I can't answer this for myself because as a native British English speaker it sounds totally wrong to me.
Best Answer
Basically, the positive anymore does not simply have the meaning of nowadays, but rather means simply quite the opposite of negative anymore. The negative anymore implies that what is described by the sentence used to be the case, and asserts that it no longer is, the positive anymore implies or asserts that what is described used to NOT be the case, and asserts that it is now.
Kindle and Sag (1975) provide a slightly more technical explanation. Consider the following:
According to Kindle and Sag (1975):
