Add new section 5.3.7

terms that are plural, verb, or other word forms of an event term (i.e. “floods”, “flooding”, “flooded” , etc…).

Unless the natural form of the term is in one of these forms, “floods”, “flooding” and “flooded” do not imply anything more as an event type than does just the word flood. Flood is actually more versatile as a corresponding alert type as the alert can pertain to all these variations. The various forms of the word flood are free to be used in other event typing schemes; however, the EMTC list will constrain such entries to its base form.
