What word has the greatest morpheme to syllable ratio? [closed]

I am curious how tightly packed morphemes can be in English words. Do any of you happen to know which English word has the most morphemes per syllable, or know how to find out?

These are the best I've found so far:

fourths (3 morphemes, one syllable)

firsts, fifths, sixths, eighths, ninths (same)

And a similar question: which word has the fewest morphemes per syllable?

I haven't thought about this one as much, but this was the best I could think of off the top of my head:

anthropomorphism (3 morphemes, 6 syllables)

You coooould do a rough search computationally. But by a process of induction, I suspect it´s not worth it:

I suspect that it will be more likely to be short words like your "fourths" example that give the highest ratio-- once you start getting longer words, where extra morphemes are added with affixes, it's rare for such prefixes/suffixes to not themselves constitute a syllable, so overall, adding more affixes won't improve the ratio but is more or less guaranteed to decrease it.

It also depends a bit on what you call a "morpheme", of course. "goes" is uniquely present tense, third person singular. So does that mean it is 4 morphemes for a single syllable? (the verb root plus the latter three).
