小さな
“小さな” means “small” in “小さな棚,” describing the shelf as small. It is placed directly before the noun it describes, as in “小さな棚.” A learner can use this pattern when describing the size of an object.
棚
“棚” means “shelf” here, the object the speaker wants to install. In “小さな棚を,” it is followed by “を” because it is the object of the action. Use it when talking about a shelf for storage or installation.
を
“を” marks “棚” as the object of “取り付けたい” in “小さな棚を取り付けたい.” It shows what the speaker wants to attach or install. A common reuse pattern is noun + “を” + action.

“取り付けたい” means “want to install or attach” in “棚を取り付けたい.” The ending expresses the speaker’s desire to carry out the action. Use this form before an object when saying that you want to install or attach something.
の
In the exact sequence “取り付けたいので,” “の” helps form a reason clause together with “で,” meaning “because I want to install it.” It connects the speaker’s purpose or reason to the request that follows. The reusable pattern is a reason clause + “ので” + request or statement.
で
In “取り付けたいので,” “で” completes the reason expression “ので,” which means “because” or “since.” The whole expression gives the reason for borrowing the drill. Use a reason clause ending in “ので” before a request when you want to sound explanatory and polite.

に
