sub-
(Latin: under, below [suc-, suf-, sug-, sum-, sup-, sur-, sus-]; used as a prefix)
Don't confuse the sur- in this element with the sur- in super-. Note: sub- regularly means "under", but it often changes its form as it retains its meaning:
The prefix sub- often becomes suc- before c: succumb.
The prefix sub- often becomes suf- before f: suffuse.
The prefix sub- often becomes sug- before g: suggest.
The prefix sub- often becomes sum- before m: sumptuous.
The prefix sub- often becomes sup- before p: suppression.
The prefix sub- often becomes sur- before r: surrogate.
The prefix, sub- is often simplified to su- before sp. Before c, p, and t; it is sometimes formed into sus-; as seen in suspect, suspend, suspicion, suspension, et al.
