Making progress by crawling (8)
I believe the answer is:
swimming
This might be a double definition.
'making progress' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'crawling' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'by' is the link.
Can you help me to learn more?
(Other definitions for swimming that I've seen before include "Doing crawl" , "Bathing" , "Moving through water" , "Travelling through water" , "Filled with tears" .)
