Took some introductory steps? (4)
I believe the answer is:
trod
'took' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'some introductory steps?' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TROD' is hidden within 'introductory steps'.
Can you help me to learn more?
(Other definitions for trod that I've seen before include "Walked (on something)" , "Walked upon" , "Trampled" , "Stepped heavily" , "Walked in a specific way" .)
