The spelling of "Gouthier" can be confusing due to its French origin. In IPA phonetic transcription, it is pronounced as /ɡu.tje/. The "ou" makes a "u" sound as in "put" and "thier" is pronounced as "tyay". This word may be spelled with a "c" instead of a "g" in some cases, as it is sometimes spelled "Couthier". However, both spellings refer to the same surname, which means "maker of quilts" in French.
The word "Gouthier" is likely a surname of French origin. It is derived from the Old French personal name "Gautier", which evolved from the Germanic name "Waldhar" or "Waldheri". "Waldhar" is composed of the elements "wald", meaning "rule" or "power", and "heri", meaning "army" or "warrior". Over time, "Gautier" or "Gouthier" became a common surname in France and was adopted by various families.
