Hello. Mainly straightforward today . But, as always, one or two that I can’t fully fathom.
Tone reflected as a prelude to foxtrot (4) . I have ?c?o and the only word I can think of is echo. But why?
And another little one: still getting stomach upset? That’ll be the shellfish.(4)) I have c?a?
So it could be crab or clam . So there’s a shellfish . But I can’t think where stomach upset comes into it

1 Phonetic alphabet echo comes before foxtrot.

2 Calm with 'stomach' upset. Clam

Many thanks, cashier. I still don’t quite “ get” clam but I’ll go along with it. I like the phonetic alphabet one. Fooled me. But that’s easily done. steven

Stomach - middle of the word upset. La instead of al. Still is calm.

E for Echo, F for Foxtrot - NATO alphabet.
Clam is from Calm, still- stomach = middle 2 letters.

Sorry, I started my reply timeously, got distracted and then finished later, in a hurry!
