About 第一
第一 is an expression in Japanese which may be used either as an adverb, or as a noun. As a noun, it will carry the meaning of 'foremost', or 'most important'. As an adverb, it can mean 'first', or 'above anything'.
To use 第一 adverbially, pair it with に. As a noun, it will usually be followed by の (when connecting nouns), or by the auxiliary verb だ, when at the end of a sentence. に will often be ommited when there is no need to put specific emphasis on a time.
Occasionally, まず 'first of all' will be paired with 第一. This may seem redundant, but is like saying 'the very first' in English.
Fun Fact
第 is a kanji that is often translated as 'number'. However, the literal meaning is a bit closer to 'position', as it refers to the place that something has within a sequence of numbers. As such, 第一 simply means '1st position'.

Sorry for necro’ing an old thread. But this grammar has been coming up in my reviews with the special rule:

Good question tbh. I think a common way would be l+tu for an isolated っ, but whether or not that’s faster than typing t+tu then hitting the backspace is probably personal preference. I think Japanese keyboards have a dedicated hotkey for it? Never used one so just speculating, I’d be curious to hear from others as well.

I didn’t realize we were able to do this on romaji input even when utilizing Windows IME! I’d probably input much faster utilizing the latter approach, but it’s really good to know there’s a way to access all of the small characters on IME as well
