A warhammer is a light fast melee weapon, designed to smash skulls and pierce armor. It typically had a metal head and wooden handle. Though variations do exist.
A frog is a metal ring hung on a leather band that you thread your belt though to hold handled weapons. (See also leather straps for sword scabbards)
Therefore, to answer your question, a warhammer in a frog is a light fast melee weapon, carried in a metal ring hung from your belt.
Short term employment of a sage is typically at 100gp per day. So even with showing your name with a different accent on different syllables. It appears you owe me 90gp. I do accept gems and magical texts in lieu of gold.
