I don't mind occasionally having to look up an obscure solution when completing The Times cryptic, but yesterday (Tuesday 26th July) for me there were too many such examples.
New to me were JARRAH, WAKE-ROBIN, RINGGIT (maybe should know currencies), TAHR, BEL CANTO and finally BEARD with a (mainly American) second definition: Resolutely oppose woman out with gay man (5)
Another Americanism was LEATHERNECK for a marine. I did check it but was fairly confident I had it right. AMBO I think I have met before but I still had to get it from the Quick Solve gismo.
I do enjoy learning new words but I also like to finish a crossword without too much help.
