The word あのう is a common colloquial expression in Japanese, often used as a filler word or a softener in conversation.
あのう is often used to express doubt or uncertainty, for example when you're unsure or hesitating about what to say next, or when you're unsure about a situation or opinion.
|Um, I can't remember the name.||あのう、 名前 が 思い出せない。anou, namae ga omoidasenai.|
|Uh, is this really okay?||あのう、 これ は 本当 に 大丈夫 です か？anou, kore wa hontou ni daijoubu desu ka?|
あのう is also often used at the start of a question or conversation in order to get someone's attention in a polite way.
|Excuse me, what time is the next train?||あのう、 次 の 電車 は 何時 です か？anou, tsugi no densha wa nanji desu ka?|
Finally, あのう can also be used to soften a statement or a request that might be considered abrupt or direct.
