”R”-letter day

“R” is the 18th letter of the modern Latin Alphabet. It corresponds to the ancient Semitic resh and is perhaps derived from an earlier hieroglyph representing a human head. From the Egyptian symbol the letter evolved into a triangular flag shape and then to a rounded “P” under Greek influence, before the descending, angled stroke of “R” was added in the 3rd century BC, giving the letter the form we recognise today. The standard English pronunciation is ar. R-words can be fun and surprising – “r” is the letter of the dictionary we turn to when we decide to open the dictionary at random! Or they can be positive and uplifting – why else would we describe a day that signifies a special significance or opportunity to us as a “red-letter day”?

Form a “Q”

“Q”, (pronounced cue), is the 17th letter of the alphabet. The letter is from the Phoenician equivalent of Hebrew koph, qoph, which was used for the deeper and more guttural of the two “k” sounds in Semitic. The letter existed in early Greek (where there was no such distinction), and called koppa, but it was little used and not alphabetized; it mainly served as a sign of number (90). Correspondingly, the root base of English Q-words is uniformly Latin and characterised by the total absence of Greek prefixes and suffixes, which is in sharp contrast to other letters. The form of the letter “Q” could have been based on the eye of a needle, a knot, or even a monkey with its tail hanging down… /q/ is a sound common to Semitic languages, but not found in many European languages. One view is that the form of the letter “Q” is even more ancient: it could have originated from Egyptian hieroglyphics. And “Q”, like “M” before it, is of course a character in the never-ending James Bond franchise.

A myriad of P’s in this pod

“P” is numerus XVI in the English alphabet letter of sequence. The letter has a special place in the International Phonetic Alphabet (IPA)…the symbol ⟨p⟩ represents a type of consonantal sound used in most spoken languages, the voiceless bilabial plosive or stop (sometimes called the unvoiced labial stop). “P” corresponds to the Semitic pe, perhaps deriving from an earlier sign for “mouth.” The early Greeks renamed this form pi(Π). The rounded shape of the “P”(“p”) is thought to be a Latin borrowing from the ancient Etruscan language. Another feature of the letter p is its use in combination with h in words of Greek origin to denote the unvoiced labiodental spirant expressed in other words by the letter f—e.g., philosophy, phonetics, and graphic (www.britannica.com)

The story of ”O” lexemes

ALDOOCDOW reaches one of the key letters in lexicon entries, “O”, the great connector of syllables. The story of “O”, the 15th letter and fourth vowel in the alphabet, is an interesting one. Circular in shape like the number zero, the letter “O” surfaces for the first time in writing systems in the Semitic languages some time around 1,000BC as a consonant (the cognate Arabic letter ayin which possibly evolved earlier from a hieroglyphic sign representing an eye). When it reached the archaic Greeks “O” morphed into the vowel we recognise in English today.
