As you see, the poster includes the lines Biɛ Wɔshwɛɔɔ and Yɛ. You can read more about it here.
The characters ɛ (U+025B) and ɔ (U+0254) are used in the orthography of various Ghanaian languages. The one we have here is presumably Akan (a cover name for Twi and the mutually intelligible Fante), spoken by about 19 million people, half in Ghana and half elsewhere. As you might expect, these symbols stand for the lax mid vowels, front unrounded and back rounded respectively. (There is a system of vowel harmony. Phonologists classify these two vowels as [-ATR], as opposed to their [+ATR] counterparts e and o.)
The IPA does not distinguish upper and lower case, although the Latin alphabet used for orthographies does. So Twi also makes use of the special upper-case characters Ɛ (U+0190) and Ɔ (U+0186).
Probably most of the Londoners who see this poster imagine that these special letters, if they notice them at all, are just fancy ways of writing ordinary e and o. Phoneticians and Africanists know better.

And literate speakers of those languages!
ReplyDeleteOK, but what does it taste like?
ReplyDeleteHard to believe that most Londoners see the ɔ as anything but a c.
ReplyDeleteSo what do Biɛ Wɔshwɛɔɔ and Yɛ mean?
ReplyDeleteYɛ can have several meanings, though in this case my guess (as a non-native speaker) is that is means `to be good.' Interestingly, `sh' is not the way the voiceless palatal fricative is written in Akan; in Akan it's written as `hy'.
