Post by Stefan RamA small iota is written beneath a long vowel, forming the
second element of a diphthong, as in ᾳ, ῃ, ῳ. Insofar it
seems to be small.
[ Meta: I do not know how you always manage to break up a thread into
two different threads - same subject, same theme - but I just stumbled
across this alt-"Not one iota" thread.]
If you were following the other [OP] thread, you will have seen that
there are two 'iotas' to contend with:
* iota the Greek letter (from c. 8 BC)
* iota-subscript (later addition, Middle Ages)
I have convinced myself (with the help of Jerry F., & PDT) that the
expression "Not one iota" comes from Matthew 5:18, and not the subscript
variant, some 1300 years later.
