succourn.

succoursuccour: [13] If you succour someone, you are literally ‘running under’ them. The word comes via Old French socorre from Latin succurrere, a compound verb formed from the prefix sub- ‘under’ and currere ‘run’ (source of English courier, course, current, etc). The original sense ‘run under’ evolved metaphorically to ‘run to someone’s assistance’, and then to simply ‘help’.=> courier, course, currentsuccourchiefly British English spelling of succor (q.v.); for spelling, see -or.
