Wilner Piquant was born in 1951.

"Piquant" is pronounced quickly as "pee-kuhnt."

Example: Those chicken wings are very piquant. :)

Piquant (adj): spicy, salty, tasty, tangy etc...

The lemonade was very piquant and hardly had any sugar in it; everyone who tasted it pinched their lips.

My dictionary has pigweed but not piguant. Perhaps you mean "piquant," as in The spices in jambalaya make it piquant, or Everyone at the exhibition was touched by the piquant photographs of rural poverty.
