Glottalization is the complete or partial closure of the glottis during the articulation of another sound. Glottalization of vowels and other sonorants is most often realized as creaky voice (partial closure). Glottalization of obstruent consonants usually involves complete closure of the glottis; another way to describe this phenomenon is to say that a glottal stop is made simultaneously with another consonant. In certain cases, the glottal stop can even wholly replace the voiceless consonant. The term 'glottalized' is also used for ejective and implosive consonants; see glottalic consonant for examples.
There are two other ways to represent glottalization of sonorants in the IPA: (a) the same way as ejectives, with an apostrophe; or (b) with the under-tilde for creaky voice. For example, the Yapese word for "sick" with a glottalized m could be transcribed as either pronounced as /[mʼaar]/ or pronounced as /[m̰aar]/. (In some typefaces, the apostrophe will occur above the m.)
Glottalization varies along three parameters, all of which are continuums. The degree of glottalization varies from none (modal voice, pronounced as /[d]/) through stiff voice (pronounced as /[d̬]/) and creaky voice (pronounced as /[d̰]/) to full glottal closure (glottal reinforcement or glottal replacement, described below). The timing also varies, from a simultaneous single segment pronounced as /[d̰]/ to an onset or coda such as pronounced as /[ˀd]/ or pronounced as /[dˀ]/ to a sequence such as pronounced as /[ʔd]/ or pronounced as /[dʔ]/. Full or partial closure of the glottis also allows glottalic airstream mechanisms to operate, producing ejective or implosive consonants; implosives may themselves have modal, stiff, or creaky voice. It is not always clear from linguistic descriptions if a language has a series of light ejectives or voiceless consonants with glottal reinforcement,[1] or similarly if it has a series of light implosives or voiced consonants with glottal reinforcement. The airstream parameter is only known to be relevant to obstruents, but the first two are involved with both obstruents and sonorants, including vowels.
When a phoneme is completely substituted by a glottal stop pronounced as /[ʔ]/, one speaks of glottaling or glottal replacement. This is, for instance, very common in British English dialects such as Cockney and Estuary English dialects. In these dialects, the glottal stop is an allophone of pronounced as //p//, pronounced as //t// and pronounced as //k// word-finally, and when followed by an unstressed vowel (including syllabic pronounced as //l// pronounced as //m// and pronounced as //n//) in a post-stress syllable. 'Water' can be pronounced pronounced as /[ˈwɔːʔə]/ – the glottal stop has superseded the 't' sound. Other examples include "city" pronounced as /[ˈsɪʔi]/, "bottle" pronounced as /[ˈbɒʔo]/, "Britain" pronounced as /[ˈbɹɪʔən]/, "seniority" pronounced as /[sɪiniˈɒɹəʔi]/. In some consonant clusters, glottal replacement of /t/ is common even among RP speakers.
Geordie English has a unique form of glottalization involving glottal reinforcement of t, k, and p, for example in "matter", "lucky", and "happy". T, k, p sounds between vowels are pronounced simultaneously with a glottal stop represented in IPA as p͡ʔ, k͡ʔ and t͡ʔ.[2]
Glottal replacement occurs in Indonesian, where syllable final pronounced as //k// is produced as a glottal stop. In Hawaiian, the glottal stop is reconstructed to have come from other Proto-Polynesian consonants. The following table displays the shift pronounced as //k// → pronounced as //ʔ// as well as the shift pronounced as //t// → pronounced as //k//.

Glottal replacement is not purely a feature of consonants. Yanesha' has three vowel qualities (pronounced as //a//, pronounced as //e//, and pronounced as //o//) that have phonemic contrasts between short, long, and "laryngeal" or glottalized forms. While the latter generally consists of creaky phonation, there is some allophony involved. In pre-final contexts, a variation occurs (especially before voiced consonants) ranging from creaky phonation throughout the vowel to a sequence of a vowel, glottal stop, and a slightly rearticulated vowel: pronounced as //maˀˈnʲoʐ// ('deer') → pronounced as /[maʔa̯ˈnʲoʂ]/.

When a phoneme is accompanied (either sequentially or simultaneously) by a pronounced as /[ʔ]/ or a pronounced as /[ˀ]/, a glottal stop modifier, then one speaks of pre-glottalization or glottal reinforcement.
See also: T-glottalization and Unreleased stop. This is common in some varieties of English, RP included; pronounced as //t// and pronounced as //tʃ// are the most affected but pronounced as //p// and pronounced as //k// also regularly show pre-glottalization. In the English dialects exhibiting pre-glottalization, the consonants in question are usually glottalized in the coda position: "what" pronounced as /[ˈwɒʔt]/, "fiction" pronounced as /[ˈfɪʔkʃən]/, "milkman" pronounced as /[ˈmɪɫʔkmən]/, "opera" pronounced as /[ˈɒʔpɹə]/. To a certain extent, some varieties of English have free variation between glottal replacement and glottal reinforcement.
Glottal reinforcement is present in some varieties of Low Saxon, most notably Twents. It usually denotes syllable reduction, and can be heard before plosives: Dat düt et can in its most extreme form be reduced to pronounced as /dʌʔˈdʏʔt/.
