Not quite. Please see my post here: About Buddhist monastic titles 😕
According to the dictionary, ayya is used for both men and women and simply means ‘Venerable’.
(m.) a lord, master; a worthy person; the venerable sir, (f.) a mistress; a noble lady; the venerable lady.
(mfn.) well-born; worthy, venerable.
ayyā is used for women only in some cases.
If this is so, that is a later usage of the word and not according to the EBTs.
Ha! I think you mean Ven. @yodha a on this forum: Dhamma doodles 😁 - #159 by yodha
Or to Ayya Sujato now
