How do you say how in Kikuyu language?

There isn't a single direct translation for "how" in Kikuyu, as the word's meaning depends on the context. Here are some options depending on what you're trying to convey:

For asking about a manner or method:

* Ndingũ (N-dee-ngoo): This is the most common way to ask "how" in the sense of "how do you...?" or "how did you...?"

* Ũthũ (Oo-thoo): This is a more formal way to ask "how" and can be used in situations like "how are you?" or "how is the weather?"

For asking about a degree or extent:

* Nĩ mũthenya (Nee moo-the-nya): This translates to "to what extent" or "how much". For example, "how much do you love me?" would be "Nĩ mũthenya ũndũ ũrĩa ũndũa?"

For asking about the quality of something:

* Ũrĩa (Oo-ree-ah): This translates to "how" in the sense of "how is it?" or "what is it like?"

Examples:

* Ndingũ ũrĩa ũrĩa ũkoragia mũthemba mũnene ũrĩa? (How do you make such a big cake?)

* Ũthũ mũthemba ũkoragia? (How is the cake?)

* Nĩ mũthenya mũingi ũrĩa ũrĩa ũndũa? (How much do you love me?)

* Ũrĩa mũthemba ũrĩa ũrĩa ũkoragia? (What is the cake like?)

It's important to consider the context and choose the most appropriate word to convey the meaning you intend.
