Somewhat blank or having qualities similar to being blank, empty, or expressionless.
From blank + -ish (suffix meaning 'somewhat' or 'having the quality of'). The -ish suffix comes from Old English and Germanic roots, meaning to make something partial or somewhat resembling.
English speakers are obsessed with the -ish suffix because it lets you express uncertainty without committing fully—'blankish' lets you describe that slightly confused, sort-of-empty expression we all make during boring meetings without saying someone is completely blank.
