What 깦 means
It is one Korean syllable, not a word with a complete translation.
Hangul combines consonant and vowel letters, called jamo, into syllable blocks. In 깦, ㄲ starts the block, ㅏ is its vowel, and ㅍ closes it. These parts show how the syllable is built; they do not spell a standalone word meaning.
Hangul was designed to write Korean speech. The court chronicle Sejong Sillok records the Hunminjeongeum project in 1443; a book with that name explaining the script was published in 1446. A 2009 paper proposes that the Phags-pa script influenced some Hangul vowel-design principles. This debated proposal concerns Hangul's design, not the origin of this individual syllable.
How do I type 깦?
With Korean input active, enter ㄲ, then ㅏ, then ㅍ.
A Korean input method assembles the block as you type and may reassign a consonant when the next letter arrives, depending on whether it starts or ends a syllable.
On the CLDR Windows layout, use Shift+R, K, V for that sequence; other Korean layouts can differ.
Neutral as a written syllable; its word-level meaning depends on the Korean text around it.

1Why can 깦 appear as separate jamo?
Hangul can be stored as one precomposed syllable block or as a sequence of conjoining jamo letters. Both represent the same syllable; whether they form a visible block depends on font and app shaping support.
