A somewhat unusual turn of phrase I heard today on BBC Radio 4 was “on the grow“. The programme was called Where England Meets Wales, and they were taking about the increase in the number of speakers of Welsh in north east Wales. The context was:
I’m not entirely sure why, if compared to Scots Gaelic or Cornish, it’s thrived, but I think it’s something that really symbolises the Welsh nation, and as a nation we’re incredibly passionate about having the language and keeping alive. What’s really encouraging is that there’s a high number of Welsh learners in every county, so it is on the grow, and it’s growing very quickly.
Have you heard this construction before?
