Four is possible in many ways:

    aiery canst dolma offal
    realo tings dampy humph
    raine scold bulgy ought
    ureas gilpy cyton conic
    lutea prosy canid cigar
    leary ungot camis humph
    stale groin dampy humph

If you're wondering what some of those words mean, Wordle (and this variant) have a big list of fake words it allows for guesses.

I think 4 is probably optimal, but my solver is still running. :) There's probably way more fours as well, my solver only prints new bests found, and this list is from progressively allowing a wider and wider search, so each result is from a separate run. I wonder how many end in 'humph'.

In case anyone is still reading this thread, I think four is now proven optimal. Short explanation: https://mobile.twitter.com/zwegner/status/148011092775217561...

Is it possible to guess in four using only real words?
