I'm not so happy this week. All normally clued solutions found and entered, and the 5 word unclued phrase found, and even the Brewer's reference and quotation. However, struggling for synonyms of 1 down (the most obvious foreign-language word which fits the bill).
My unclued entries, which should be described by 12ac, 22dn, 41ac are as follows
16dn ?EKEL
23dn ?ENE?EN?
26dn ?PH?RS?N
I've no idea where to go from here.
