>> As a noun, it's a second helping of a dish (not the vessel itself, can't help that, but what's poured inside) during a meal.
>Excuse the pedantry, but In the example you used, it's an adjective.

English ---- what a language!!!!

It's a noun
a measure of time equal to one sixtieth of a minute
a measure of distance equal to one sixtieth of a minute of longitude/latitude
a representative of one of the principle (pal?????) participants in a duel
a second helping of a menu item of a meal (i.e. "I'll have seconds of that")

It's a verb
to assist a participant in a duel
to additionally sponsor a motion according rules of procedure

It's an adjective
a second helping, etc.

I can't believe that English is unique in this multiple use of words. I would love to see equivalent examples of French, German, Spanish (languages I mimimally understand) as well as the various other languages represented here.
