		Description:	"ij" for "ee/e" substitution for strong verbs, whose verb primitives end on "ij" and that are followed by one arbitrary consonant.
		Example verb:	2.	blijven (strong verb)
		Application:	-	the verb's verb primitive ends on "ij" and is followed by a consonant.
			-	the "ij" is replaced by a double, respectively a single "e", e.g. "wij bleven", not "wij blijvden".
