Thamesmead (English)

Where does "Thamesmead" come from?

The name Thamesmead is formed in English by combining Thames and mead[1]. The river element traces back through Middle English 'Temese'[3] and Old English 'Temes'[3] to Latin 'Tamesis'[3], which ultimately derives from Proto-Brythonic '*Tamesis'[3]. This name likely stems from Proto-Celtic '*tamesās'[3], meaning 'river, waters' or literally 'darkness'[3], rooted in Proto-Indo-European '[t]m̥Hes-'[3]. The second element, mead, descends from Middle English 'mede'[2], Old English 'medu'[2], and Proto-Germanic '*meduz'[2], ultimately reflecting the Proto-Indo-European root '*médʰu'[2] meaning 'honey' or 'sweet drink'[2][4].

Open questions

The river name may alternatively derive from a Proto-Celtic root meaning to melt or flow, or from an unknown non-Indo-European root. [3]
The Proto-Indo-European term for honey or sweet drink may have been borrowed through Proto-Northeast Caucasian or related to Proto-Semitic. [6]
