Basic colors: Asking about tshirt color options

💬 [この] must come right before a noun: [このTシャツ], [この色]. You don't use it by itself for "this one" — for that, use [これ].

💬 [この] has to be followed by a noun, so [このTシャツ] is a complete unit meaning "this T-shirt." Swap the noun to make new phrases like [この色] or [この店].

💬 [ほかの] means "other" and usually comes right before the thing you're talking about: [ほかの色], [ほかの商品]. On its own, [ほか] can mean "something else" or "the rest," but [ほかの] needs a noun after it.

💬 Put [の] after one noun to let it describe the next one: [ほか] + [の] + [色] = "other colors." You can reuse that pattern in lots of shopping phrases, like [夏] + [の] + [服].

💬 [あります] is used for things existing or being available, so in shops it often means "we have it." You'll hear it for stock and options: [赤もあります] or [大きいサイズもあります].

💬 Put [か] at the end to turn a statement into a question: [あります] → [ありますか]. In careful speech, you often don't need rising intonation because [か] already marks it.

💬 [ありますか] is a very reusable shop pattern for asking whether something is available. You can put the item before it: [赤はありますか] or [大きいサイズはありますか].
