A thorn is a sharp prickled growth on flower stems, found on roses.
Thorn is also a lost letter from Old English, written as þ, it was also in runic poems in Norse and Old Swedish and has survived in Icelandic. Modern English merges it into the 'th' sound.
The idiom ‘thorn in the side’ refers to a question or problem that is physically insistent, calling attention through interventions in proprioception and other means.
These confluences of flowery prickles and lost letters, fragrant punctum and voiceless aporia, are guides for the podcast and for the School overall.
