Compound words: what real compound word is composed of most words?

Handcraftsmanship

^{(if you're ok with suffixes like this)}

From Which is correct: "So far as I know" or "As far as I know"?, I offer: Insofar.

In the mean time, here are some more offerings of words that are made up of three or more sub-words that are considered standard English or have entered the common vernacular (all words pass the stackexchange spellchecker):

• Whatchamacallit (What-you-may-call-it)
• Thingamajig
• Thingamabob
• Plainclothesman
• Nevertheless
• Notwithstanding
• Theretofore
• Newspaperman
• Whatsoever, Whosoever, Wheresoever, Howsoever
• Insomuch (to go with 'insofar', mentioned above)

Here's the list I have: albeit, heretofore, howsoever, inasmuch, insofar, insomuch, nevertheless, nonetheless, notwithstanding, nowadays, whatsoever, wherewithal, whosoever. Some have suggested whensoever and wheresoever, but those are used (if ever) primarily in legal writing. I seem to remember a friend using a four-word closed/solid compound not too long ago, but can't recall what it was!

Words are made up of morphemes, which are either free or bound morphemes. Some words comprise of a free morpheme only like the word establish which comprises of a single free morpheme. Disestablish, on the other hand is a word made up of two morphemes, of which dis is a bound morpheme and establish, as stated before, is a free morpheme. By the same token, we can analyse other bound morphemes like ar, ial, iz, im, and so on. As such, disestablishmentarialism, etc are wordssss.
