Etymology
Origin of hobby1
First recorded in 1325–75; Middle English hoby(n), probably from Robin, or Robert ( cf. hob 2), used as horse's name, as in dobbin
Origin of hobby2
First recorded in 1400–50; late Middle English hoby, from Middle French hobé, variant of Middle French, Old French hobel (compare French hobereau ), probably noun derivative of hobeler “to skirmish, harass,” perhaps from Middle Dutch hob(b)elen “to turn, roll”; compare Dutch hobbelen “to rock, jolt” ( cf. hobble)
Explanation
A hobby is an activity that you do in your spare time for fun. Your hobby may be putting together model train sets and driving your mom crazy from all the noise. In the 13th century the word hobby referred to a small horse or a pony. It later came to describe a toy horse — a hobbyhorse. It’s from the hobbyhorse that the word’s modern sense of “favorite pastime” evolved. A hobby is something that you do for fun — not money — and you typically do it fairly regularly. Collecting stamps, growing roses, reading — any of these can be hobbies.
