1. The deepest river in Great Britain

Краткое пояснение:

Пошаговое решение:

1. The question asks for the deepest river in Great Britain.
2. Research indicates that the River Severn is the longest river in Great Britain, but not necessarily the deepest.
3. Further research is needed to confirm the deepest river. Some sources suggest the River Spey in Scotland as being very deep. However, definitive confirmation of the 'deepest' river can be challenging without specific depth measurements across all major rivers. Given the context of a crossword, a commonly known fact is usually expected. The River Thames, while famous, is not typically cited as the deepest. The River Trent is also a contender for length and volume.
4. Upon further investigation, there isn't a single river widely recognized and undisputed as the 'deepest' in Great Britain in the way that Loch Ness is known for its depth. However, if this is for a crossword, there might be a specific intended answer. Without further context or crossing letters, it's hard to be definitive. If 'deepest' is interpreted as 'longest' or 'most significant', then the Severn would be a candidate. If it refers to a specific known depth, information is scarce.
5. Considering common crossword answers related to British rivers, and the difficulty in definitively identifying the 'deepest', it is possible the question intends a more general answer or is based on a specific, less common fact.
6. Let's reconsider the length. The River Severn is the longest. If 'deepest' is a proxy for 'largest' in terms of water volume or depth over a significant stretch, the Severn is a strong candidate.
7. However, some sources point to the River Spey in Scotland as being very deep in parts.
8. Given the ambiguity, and aiming for a plausible crossword answer, 'Severn' (longest) is often used when 'deepest' is implied for major rivers, though not strictly accurate. Let's search for
