The real problem is the second element, -ledge. There are many, many Middle English spelling variants of knowledge, including knoulecch(e), knouelech(e), cnoulech, knowlesche, knoleche, and later spellings, including knoulegge, knoleg(e), knoleige, knowlegege, knaulag(e), cnaulage. The earlier spellings indicate a pronunciation with the same ch sound as in leech or letch; the later spellings, for example, knaulage, originating in the northern dialects and implying a pronunciation with a soft g (as in gem ), appear in the 15th century.
The Middle English element -lech(e) is a very rare noun suffix from unrecorded Old English -lǽce, a variant of -lāc, a noun suffix indicating action or proceeding. The original suffix survives only in the noun wedlock (Old English wedlāc “pledge, security, espousals,” Middle English wedlōk “institution of marriage, the married state”), proving, once and for all, that wedlock is not related to the word lock.
