lumpish

Partly: from Late Middle English lumprissh, lumpryssh (“of a somewhat lumpy consistency”), from lumpe (“mass of material; excrescence, swelling; mass of people, crowd; useless person”) or lumpred (“piled up or twisted into lumps”) (both possibly related to Proto-Germanic limpaną (“to glide; to go; to hang limply”), from Proto-Indo-European *(s)lembʰ- (“to hang limply”)) + -ish (suffix forming adjectives with the sense ‘of the nature of; similar to; somewhat’); and * from lump (noun, verb) + -ish. Compare English lumber.
