Usage notes
Slightly is often used by the English to mean almost the opposite, something like rather. For example, "The big picture here of course is that still staggeringly low numbers of these migrants are being hired though, isn't it? And despite these rather positive tales we've just heard, there seems to be a broader, slightly grimmer picture which perhaps will have a lesson for other countries thinking of receiving migrants." (Ed Butler on BBC Business Daily, Sept. 23, 2016)

– Slight, Neglect. To slight is stronger than to neglect. We may
neglect a duty or person from inconsiderateness, or from being over-
occupied in other concerns. To slight is always a positive and
intentional act, resulting from feelings of dislike or contempt. We
ought to put a kind construction on what appears neglect on the part
of a friend; but when he slights us, it is obvious that he is our
friend no longer.
Beware . . . lest the like befall . . . If they transgress and slight
that sole command. Milton.
This my long-sufferance, and my day of grace, Those who neglect and
