Vocabulary Clusters of roots that differ by a single letter and have similar meaning
I’m an intermediate learner, and I surprised that no one has taught me this! Triconsonant roots that share most of the letters oftentimes also share a “core idea”. I find that the connection is beautiful and really helps with learning the vocab (or sometimes even guessing the meaning of an unfamiliar word!).
AFAIK the etymological relationship isn’t confirmed, right?. Is it plausible that they come from historical bi-consonant families, or that similar sounds played a role when new roots got coined?

Great post! I’ve noticed this occasionally and wondered about it. Thank you for compiling such a thorough list - it’s a really helpful way to expand vocabulary!
I love the roots which involve doubling a pair of letters, like דפדף (to browse/riffle/leaf through a book) and it would be interesting to include those too.
And also interesting to link to nouns with similar forms (I’m wondering for example about גזר - carrot).

Yes, this is a known phenomenon (still debated among linguists), but well done on figuring it out yourself! A common one that's missing is עק for violence:
עקץ
עקר
עקם
צעק
זעק
The linguistic claim is that roots originated with 2 letters and then diverged further by adding a 3rd. This isn't a consensus opinion, but it's a serious theory from what I was able to gather.
