It may create a stir at mealtime (8)
I believe the answer is:
teaspoon
'it may create a stir at mealtime' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'stir' relates to this answer.
'it may create a stir at mealtime' is the wordplay.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'may create a stir' becomes 'spoon' (I've seen this before).
'at' means one lot of letters go next to another (I've seen this in other clues).
'mealtime' becomes 'ea' (I can't justify this - if you can you should give a lot more credence to this answer).
'spoon' after 'ea' is 'easpoon'.
't'+'easpoon'='TEASPOON'
Can you help me to learn more?
(Other definitions for teaspoon that I've seen before include "Five millilitres (cookery)" , "Small item of cutlery (8)" , "It creates a stir" , "Kitchen utensil able to hold about one fluid dram" , "Domestic stirrer" .)
