ʖ

Johnston (1913) created ⟨cˈ⟩ or ⟨c̓⟩ for a dental click, ⟨cˌ⟩ or ⟨q̓⟩ for a 'palatal' (alveolar) click, ⟨ˌɔ⟩ or ⟨x̓⟩ for a lateral click, and ⟨ˈɔ⟩ (approx. ⟨ʖ⟩) or ⟨q̓c̓⟩ for a palatal click. When Jones adopted Johnston's system for the IPA lateral click, he swapped the letters because Johnston's lateral letter conflicted with ⟨ʔ⟩, the IPA letter for glottal stop.

ʖ

1. (pre-1989 IPA) the forward release of a lateral click; superseded by ⟨ǁ⟩.
2. (superscript ⟨𐞼⟩, IPA) [ʖ]-coloring such as the lateral release of a click; or a weak, fleeting or epenthetic [ʖ]-release.

In IPA, ⟨ʖ⟩ is technically only the forward clicked release, not the entire consonant. A full transcription of a click consonant requires a second letter to specify whether the rear closure is velar or uvular, and whether the click is voiced or nasal:

	Velar	Uvular
Voiceless	k͜ʖ	q͜ʖ
Voiced	ɡ͜ʖ	ɢ͜ʖ
Nasal	ŋ͜ʖ	ɴ͜ʖ

The tie bar may be omitted, or the accompanying letter may be superscripted: ⟨ᵏʖ ᶢʖ ᵑʖ 𐞥ʖ 𐞒ʖ ᶰʖ⟩.

If the order is reversed, e.g. ⟨ʖ͜q⟩, that may imply that the velar or uvular release is audible (delayed release).

Beach used simple ⟨ʖ⟩ for the Khoekhoe voiceless oral click [k͜ʖ] and ⟨𝼎⟩ for the voiced nasal click [ŋ͜ʖ].
