Curious about lacheko, I checked my dictionary and came across 'laches' an English word I had never heard before.

la·ches noun \ˈla-chəz, ˈlâ-\
plural laches
Definition of LACHES
: negligence in the observance of duty or opportunity; specifically : undue delay in asserting a legal right or privilege
Origin of LACHES
Middle English lachesse, from Anglo-French laschesce, from lasche lax, ultimately from Latin laxare to loosen — more at lease
First Known Use: 14th century


My 1934 dictionary had many other meanings; laches is laziness, indolence, negligence. In fact, just about every male fault except being violent and leaving the toilet seat up.

I wonder if, in port cities, the idea of 'laches' as laziness was wedded to -ico to produce 'lacheko,' a lazy man.
