def specialTitleCase(words):
	# written by joedf (Feb. 2020), loosely inspired from https://github.com/gouch/to-title-case
	# 1. assumes a list of short words to change to lower case
	# 2. assumes short words are preceded by ' ' (or brackets), so that any "starting" ones are still capitalized.

	sWords = re.sub(r'[\(\[]',(lambda x:x.group(0)+' '),words)

	# Avoid issue of title() capitalizing "2-part" tokens joined by a hyphen on an apostrophe.
	# Also allows for "intentional" captilizations
	sWords = ' '.join([word if bool(re.search(r'[A-Z]',word)) else word.capitalize() for word in sWords.split(' ')])

	# titlecase with short words lowercased.
