And in fact, does socio-economic background tell a teacher about a child‘s intelligence/behaviour??
That wasn't what I said, but intelligence tends to be hereditary. Socio-economic background is likely to affect the achievement of a child.
If you like a name, fair enough, but the names tend to be trend-led, often inspired by a celebrity (Keira, Scarlett, Saoirse...)
If you use a name from another language, and misspell it or mispronounce it, that's up to you, but when that name becomes mainstream, it sort of ruins the name.
Names I think that this has happened to include Caoimhín, Michele, Rhys, Dylan, Siân, Esmée and Jadon.
