How do you say hounds tooth in Gaelic?

There isn't a single, universally accepted translation for "houndstooth" in Gaelic (as there are several Gaelic languages). The best approach would be to translate it descriptively. You'd need to specify which Gaelic language (Scottish Gaelic or Irish Gaelic) and then describe the pattern.

For example, you could use phrases describing the pattern:

* Scottish Gaelic: Something like "patrùn fiaclan-choin" (pattern of dog-teeth) might work, although it sounds a bit clunky. A more natural-sounding option might require more context (e.g., "aodach le patrùn fiaclan-choin" - clothing with a dog-teeth pattern).

* Irish Gaelic: Similarly, "patrún fiacla madraí" (pattern of dogs' teeth) could be used, but again, it's descriptive rather than a direct equivalent. Again, adding context like the type of garment would improve the phrasing.

Because "houndstooth" is a specific textile pattern name, there's no direct translation. A descriptive phrase is necessary.
