20a Instrument is one not working-engineer needed(8)

[scorpiojo]

Is there a crossing clue, chalky?

[Jackdaw33]

You do make it difficult for us Chalky. A few letters here and there would not go amiss

[iminoz]

Tenoroon?
anagram of 'one not' +or
OR means 'other ranks', not sure if that equates to engineer

[Jackdaw33]

Nice try oz, but no cigar. I can't solve it without a few cross letters but Tenoroon is unknown to me.

20a ???A????
21d Feline once caught rodent outside (3,3)

[iminoz]

21d Rex cat

[Jackdaw33]

That parses beautifully but I have never come across the term. Tom Cat, yes.

[scorpiojo]

Can anyone make triangle work?

[iminoz]

JD- otherwise known as Cornish Rex, strange looking ctitters

[iminoz]

err..critters

[scorpiojo]

Organ is E?

[Jackdaw33]

Sorry, Scorps, no. Not even sure yet if we are looking for a musical instrument.

[iminoz]

one minus 'on' = E?

[Buenchico]

Jo:
I'm rubbish at this but it occurs to me that a 'trial' version of something is one that's not fully working. Add 'eng' (abbreviation for 'engineer') to get 'triangle', possibly???

[scorpiojo]

They are, imonoz

[scorpiojo]

Dunno, Chris....perhaps chalky will tell us where the r fits....

[iminoz]

I think it' organise as jo says
instrument=organ +is + (on)e

[chalky2850]

Thank you,20a ?R?A?I??

[scorpiojo]

Oops, *iminoz

[Jackdaw33]

Probably right. Parsing is good but I would never have considered organise (definition) to be a true synonym of engineer, or vice versa, I cocked that up.
