ㅎ

ㅎ is one of the Korean hangeul. The Unicode for ㅎ is U+314E. It has two pronunciating forms [h] and [t̚]. It sounds as [h] in initial or (total or full) onset position (하), intervowel position (partial onset (아하) or coda with a previous vowel in the same syllable block and followed by an onset vowel from another block (아[...]아앟아) or pseudonset (앟아)) and in a coda following a consonant (받침) before an onset vowel in the next syllable (않아). It assimilates via aspiration as explained below in codas before plosive consonants; if ㅎ it is a full coda (the end of the speech temporarily or finally) it would sound [t̚]. (앟)

Hangul
Korean name

It represents the aspirated phoneme par excellence. In Korean language, this takes form as a consonant. It is not the aspiration representative consonant but the one following Korean phonology and its idiosyncrasy as well as phonotactics, in this case [h]. It could be understood as the aspiration generator (ㅇ glottis ideogram plus aspiration line, pure aspiration with glottis symbol base; similarly, original [ŋ] was ㆁ, the upper small stroke represents velarity; ㅇ meaning voicing phonemes, vowels as the jamo scheme is always CV flow, as the general language systems are too, based on a sound flux clogged and perturbed) since it affects via assimilation almost all Korean phonemes and the whole group of plosives in the majority of phonologic circumstances. Despite the fact ㅎ can act as a glottal stop in 'uncared' and fast speech or even pass omitted, the pure aspiration (velar-approximant) is observed between vowels, which is in an intervocalic locus. As the archetypal aspiration it comprises, muting process occurs in the same vein as Latin divergences, dialects and allophones for [h], which were [f]-ish phonemes at first in some cases, showing a muting and lenis gradient towards the common point of minimal articulatory effort. Besides, it has an 'extralinguistical' use: an archetypal of laughter like the ones found in many different language groups such as: (ㅎㅎ or 흐하...)-->([x], a more fricative variant for aspiration) jaja (Spanish) /'xaxa/; xa-xa (Russian) /'xaxa/; haha (English, French and peninsular Portuguese) /'haha/; はは (or more informal, denoted by katakana characters, less traditional and renewable ones, not so conservative: ハハ) (Japanese) /'haha/; kk[...] (indefinite or the usual 4 letters, not as the typical periodic 3-set (triad or triplet) or 3-period aggrupation for the representations mentioned above) (Brazilian Portuguese dialect, American Portuguese) /k.k.k.k./ (dots representing glottal stops as there is no vowels, not even 으; Korean has a similar rendering (graphemic and phonetically): ㅋㅋㅋ (unofficial form, since it does not contain the vowel, thus leaving the consonant block scheme incomplete) (metalinguistic experiments such as single and repeated letter-phonems (jamos) and diphthongs are allowed by korean keyboard, not a problem for most of alphabet keyboards; ㅃ ㅍ ㅠ ㅐ ㅢ ㅞ) 크크크크 and the rest of monophthongal-vowel combinations are permitted, hence enabling Korean speakers a extensive selection of proprioceptive laughs pictured in jamos, a 'vast' number of possibilities in which to express joy depending on the contexts. Nonetheless, 카 /ka/ is the most bountifully used, maybe an unwilful or arbitrary consensus. Esperanto, Nepalese, Arabic, Somali, Turkish, Swahili and Hawaiian (with only 12 phonemes in its alphabet) share /'haha/ structure even the prosodic grave accent.

Lastly, ㅎ affects, most importantly, to oral plosive consonants in such a way that they migrate upwards in the aspiration gradient, as explained and illustrated in "ㄱ" entry (only in Spanish entry). ㅎ or the plosive (plosives counting as one in double(d) or emphatic cases, not gemination ones, 쌍) located in the coda or in 받침 position change plosives (codal or onset) from lenis to fortis but better described, from emphatic or sounded to aspirated. ㄲ>ㅋ, ㄱ>ㅋ, ㅋ=ㅋ. It is analogous to codal emphasis processes from a path approach but not homologous. 윽그 > 윾으 = 으끄. 잇도 > 이또. Any codal oral plosive has the property of emphasising another oral (onset) plosive. 을나 = [을나] but 은라 > 을라 thus geminated as seen in natural and byproduct double jamo syllable conformation. 앋마,앗마 > 안마 (all codas obviously consonant, assimilate to "ㄴ" when followed by "ㅁ" in onset quality; they only assimilate as ㅁ if codas are ㅁ or ㅂ (ㅃ cannot be coda and 쁘 counts as another mora (timing, or chroneme); if ㅁ acts as a coda, all coda plosives are pronounced as pristine and genuinely even with a more fortis and aspirated or silent overtone; interestingly enough, ㅍ codas do not behave as ㅂ, as they lose sonority and they are further from its nasal counterpart, ㅁ: ㅁ > ㅃ > ㅂ > ㅍ (the decreasing symbol was used as a linguistic inflection or evolution, it would be < since it belongs to an aspiration gradient or succession) An extra line in ㅂ and another one in ㅍ represents, respectively, the tenseness due to lips pressure not being funneled apart thorough the nasal cavities (nasal route) the moment before ejecting sounded air, and the self awareness of aspiration passing through the palate and later through the lips; mote that Korean nasal consonants ㄴ & ㅁ were the first to be designed as seen in the XVI century renewed alphabetic order, before their counterparts ㄷ and ㅂ; that is the reason why there was no other line added above ㅁ but lowered, as a way of sparing space, later on being written above obtaining again a square but in order not to create confusion between ㅁ and ㅍ, lines get out, respecting the proprioception rule; similarly, ㄴ had the diacritics segment adjoint forming a easily recognisable geometric composition. Returning to gemination, ㄴ doubles in a typical way widespread through the language world, creating a microglottal stop and releasing the full airflow seconds later (it normal for a vowel hiatus or glottal stop to be immediate) with a consonantic (the one involved in the gemination process) charge thanks to reverberation during those microseconds, hence producing a geminative aspiration (could be plosive or vaccumish). ㄴ is found in both ㅁ and ㄴ cases as it is the result of nasalising an occlusive (partially, continuous flow in ㄹ) consonant (all except for ㄹ which can be transformed into ㅁ as well) elsewhere, not in the lips as for ㅁ, even the palate for codal ㅅ assimilates as ㄴ (nasal occlusive, forced as 'unconsciously' as knowing where to locate the tongue in each genuine phoneme, to be articulated in the alveolar ridge as for a regular ㄴ). The only noticeable difference between an emphasized coda and a non-so one is the chroneme period, a little smaller for the first cases, being neutralised their original phonologic value along with its remarkable and distinct sonority. A not so uncommonly unnoticed fact is the appreciation of coda ㅅ as a ㄷ when assimilating with ㅎ, functioning as a ㅌ normally aspirated. 읏해 > 읕애 = 으태.
