workshop
/ˈwɜːk.ʃɒp/noun
A room, usually of modest size, where things are made or repaired by hand or with light machinery.
Example sentence
- “She repairs antique clocks in a small workshop behind her house.”
Also a hands-on training session: 'a writing workshop'. That meaning has spawned a verb: to 'workshop' an idea is to develop it in a group.
