Taw

Taw, tav, or taf is the twenty-second and last letter of the Semitic abjads, including Phoenician Tāw , Hebrew Tav ת, Aramaic Taw , Syriac Taw ܬ, and Arabic Tāʼ ت (in abjadi order, 3rd in modern order). Its original sound value is /t/.

The Phoenician letter gave rise to the Greek tau (Τ), Latin T, and Cyrillic Т.

Origins of taw

Taw is believed to be derived from the Egyptian hieroglyph meaning "mark"

Hebrew tav

Hebrew spelling: תָו

Hebrew pronunciation

The letter tav in modern Hebrew usually represents a voiceless alveolar plosive: /t/.

Variations on written form and pronunciation

The letter tav is one of the six letters which can receive a dagesh kal diacritic, besides bet, gimel, dalet, kaph and pe. Three of them – bet, kaph and pe – have their sound values changed in modern Hebrew from the fricative to the plosive by adding a dagesh. In modern Hebrew, the other three – including tav – do not change their pronunciation with or without a dagesh, but have had alternate pronunciations at other times and places.

Tav (number)

In his work on set theory, Georg Cantor denoted the collection of all cardinal numbers by the last letter of the Hebrew alphabet, ת (transliterated as Taf, Tav, or Taw.) As Cantor realized, this collection could not itself have a cardinality, as this would lead to a paradox of the Burali-Forti type. Cantor instead said that it was an "inconsistent" collection which was absolutely infinite.

Taw (locomotive)

Taw was the name of a Manning Wardle 2-6-2T locomotive which was built in 1898 for Lynton and Barnstaple Railway. Taw was scrapped in 1935

Taw, like all the locomotives on the L&B, was named after the River Taw, a local river with a three-letter name.

The tradition of naming L&B steam locos after local rivers continues into the 21st Century, with Lyd, a replica of Lew (the fourth locomotive built to this basic design), operational on the Ffestiniog railway and the Welsh Highland Railway

A 7.25 inch gauge version of Taw was built by J. Horsfield in 1999 and runs on the Eastleigh Lakeside Railway.

Closer to the L&B, the railway's trust currently owns one steam locomotive - renamed Axe - which, although it did not serve on the historic L&B, has been restored for use on the new line, currently based at Woody Bay.
