The very base of the vocabulary (44 items) has a duplication

[kornai]

=agt, =at, =dat, =for, =from, =obl, =pat, =poss, =rel, =to, all, also, an, angry, before, can/1246, cause, characteristic, color, country, er, female, food, for, has, human, identity, inherent, is_a, lack, male, monk, next_to, not, number, or, other, part_of, person, real, round, speak, target, want

The duplication is between =for and for, both of which appear in several places.

Also suspicious: human/person (they have the same definition, just like permit/allow,
but the current algorithm doesn't prune these well).

[makrai]

• =FOR and FOR: I will send a pull request replacing =FOR with =TO
• human and person are both defined as man/659, this is OK in 4lang. This is a bad property of this 44-element DV, but such sub-optimalities may appear as the problem is NP-hard.
• permit is defined as allow, which in turn is defined with more basic elements (=AGT SAY =DAT[=PAT[can/1246]], say CAUSE =DAT[=PAT[can/1246]]) this is also OK
