I should add that my son was about 10 when he learned to spell that.

Also, “pedantic." I told him, once, if he insisted on BEING it, he’d have to spell it. Now, instead of telling him when he’s being pedantic (rare, these days!), I have only to say, “Spell it." He always says “no." I’m waiting for the day he catches himself first, and just says, “no" before I can open my mouth.
