[geo0939]

27- Proposer

[ulysses100]

5dn unbounded

[geo0939]

Could be Proposes

[shaneystar2]

Unbounded
Proposes

[shaneystar2]

Crests ...I think that white horses are the crests of waves

[starmack]

5D Deffo going to go with Unbounded.

27A Proposer/Proposed makes sense to me from that clue.

23D Crests also seems good BUT would not link with Proposer/Proposed...... So anything else wlecomed on that one

[shaneystar2]

Does crests link with proposeS ?
Suggests is present tense ..proposed ..past tense and proposer a noun

[cc1]

5d unbounded ?

23d choppy ?

not sure of either though!

[shaneystar2]

According to Chambers a "white horse" is a white topped wave ..the tops of waves are called crests ...this would tie in with "descriptive of the sea".

[starmack]

Crests makes total sense to me...but it doesnt fit if Proposer/Proposes is correct, as I believe it to be.

Choppy might fit but, again, it will give 'grief' with another linkage.....

Will revert on this if I stay stuck!

Thank you for all your help.
