oven

I'm a little stuck... Click here to teach me more about this clue!

'baking receptacle' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?

'round five measure' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'five' becomes 'V' (Roman numeral).
'measure' becomes 'en' (en is a unit of measurement used by printers).
'o'+'v'+'en'='OVEN'

Can you help me to learn more?

(Other definitions for oven that I've seen before include "Place for burning" , "Part of a cooker" , "Chamber for baking" , "Cooking device" , "Small kiln" .)
