| Comparing the list against the Official Scrabble Players Dictionary, only Fiji and Iraq have no playable substrings. Now, of course, you might not want to accept "na" and "al" as words (they're Scrabble-legal, but I admit I have no idea why). But in terms of more common words: Australia and Austria have US, Egypt has GYP, Kenya has KEN (meaning "to know"), Laos has LA, Libya has BY, Mali and Burma have MA, Algeria and Syria have RIA, Colombia and Serbia and Saudi Arabia have BI, Comoros has OR, Ethiopia has HI and PI, Liberia has BE, Venezuela has EL (the train), Greece has RE ("about"). (That leaves the ER in Niger, the NA in Nauru, and the AL in Tuvalu.) |
