People ask how to say it. Some of them ask apologetically, as if they have missed something obvious. They have not. The word gives you nothing.
That is not a flaw in the name. That is the whole reason the app exists.
Sound it out
Every parent has said it. Every teacher has said it. Sound it out.
It is the single most common piece of spelling advice in English, and for a large part of the language it is actively wrong. English does not reliably encode pronunciation in its spelling, and it does not reliably encode spelling in its pronunciation. The mapping is broken in both directions, and children work this out long before adults will admit it.
Take my son. He writes definately. He has sounded it out. He has done exactly what he was told - and doing exactly what he was told is what produced the error.
A cross is a dead end. A pattern is a route.
Here is the same wrong word, marked two ways. The difference is not the score. The difference is whether anything happens next.
Fix the rule and you fix the next forty words. Mark the cross and you fix one word, badly, until Friday.
Live, and live
Linguists call words like this heteronyms: same spelling, different pronunciation, different meaning. English is full of them, and once you start noticing them they are very hard to stop noticing.
You resolve these instantly and unconsciously, from context, and you have done it so many thousands of times that you have forgotten you are doing it at all.
A child has not forgotten. A child is doing it consciously, slowly, and often wrong. And when we hand them a spelling list, we usually hand them the word on its own - stripped of the context that was doing all the work.
Why the ambiguity is the point
I could have picked a name that resolved cleanly. Something with no second reading, nothing to explain, nothing to trip over. I picked one that trips.
Because both readings turn out to be true, and I did not plan that. I noticed it afterwards.
Live, as in real time (/laɪv/). Photograph the handwriting. Get an answer back now, while the child is still sitting there. Not a report next term. Not a mark in a book that comes back on Thursday.
Live, as in what you live with (/lɪv/). Spellings are not an exam topic. They are the words in the letter, the form, the message, the application. They follow you around for fifty years.
Two readings, both correct, and no way to choose between them from the spelling alone. That is English. That is precisely the thing that makes it hard, and putting it in the name felt more honest than pretending otherwise.
The pronunciation, for the record
Both. Say it however you like.
I have heard it both ways - from teachers, from parents, and once from an occupational therapist who said one version, corrected herself to the other, and then laughed and said the confusion rather made my point for me.
It did.
English spelling is not a system that rewards guessing. A name that quietly demonstrates that is doing more work than a name that does not.
If you have ever watched a child sound out a word carefully, correctly, and get it wrong, you already know what this is for.
