Two American cities. Perhaps that qualifies as a theme?
Across
| 1 | MINNEAPOLIS – (pile, mansion)*. “Gothic” is somehow the anagrind. |
| 7 | S,CREW,UP – Really an Americanism – at least I only learnt it in the states. But I guess it’s been exported. |
| 8 | FLANNEL – double meaning: also means the verb: to “soft-soap”. |
| 10 | OS,MAN – OSMAN founded the Turkish Empire in the 13C. |
| 11 | L(EAVES) OUT – pretty meaningless surface. “Yobbo” is Britslang for LOUT – derived from reverse of boy. |
| 12 | TRADE WINDS – nice charade with “craft” shifting from its nautical surface to TRADE. |
| 16 | HAKE – hidden in “…locH, A KElt”. By the way, “kelt” is a kind of salmon so the surface is quite elegant. |
| 21 | IDEN(TI)CAL – Iceland* contains rev(“it”). “Brewed” is a better anagrind than gothic. |
| 24 | T[asted],ANGELO – TANGELO (tangerine,grapefruit) cropped up recently in a similar charade: this one works a little better since it doesn’t involve a boxing trainer! |
| 25 | B,APTISM – B[ishop] followed by (is at, PM)* — though I don’t think it’s surprising that bishops show up for baptisms, is it? So not quite an &lit. |
Down
| 2 | NO W,ON,DER – Not much cryptic German is needed other than DER (“the”) and the occasional number. |
| 3 | E(X,P)EL – symbols for unknowns (“indefinite”) are typically X, y, z. |
| 4 | PUFF (A,DD)ER – a PUFFER is in fact a “steam-engine”. Another common abbreviation is DD for Doctor of Divinity. |
| 5 | LOADED – double meaning: I actually like this clue because “tight” in the drunk sense is a Britishism and LOADED in the same sense is originally American. |
| 6 | SAN J(OS)E – the other American city: jeans* contains OS: more cryptic shorthand for a sailor (“ordinary seaman”). Others are tar, AB. |
| 7 | SHORT SH(R)IFT – charade: “neat” is SHORT (as in “concisely”) and SHIFT for “move” contains R[ook]. |
| 9 | LET OFF S,TEAM– where “LET OFFS” is the noun for “being allowed to go free”. |
| 13 | IRON CROSS – The German military award that kind of went out of style in 1945. |
| 15 | CRACK,POT – Nice to see this clued without reference to CRACK cocaine. |
| 17 | KEEP,NET – rev(peek=”look”) , rev(ten=”number”). KEEPNET is a Brit term for a net to keep your catch alive while you’re still fishing. |
| 19 | P(ANNIE)R – A secondary meaning of the definition: “dosser” is simply PANNIER according to Chambers. (see the comment below). Collins supports this as well. |
| 20 | ST(R)EAM – definition is “fly” as in STREAM a banner in the wind: to STEAM ahead is to go quickly. |
| 22 | L[ose],I,BRA – Popular cryptic “supporter” the BRA is. |
19D a dosser is a pannier
yeah — just checked Chambers (which I should have done last week!). I’ll update… thanks!
