Vocabulary That Fits the Job You Actually Do
Most word of the day services hand everyone the same word. There is a sensible reason for that and it is the same reason it does not work very well.
The sensible reason is that a good general word is a genuinely nice thing to receive. Petrichor is lovely. Sonder is lovely. You read it, you feel a small pleasure at the existence of a word for that and you go and make coffee. Two weeks later somebody says petrichor to you and you have to reach for it. Not gone exactly, but not yours either.
Now think about a word you met at work. Not a word you studied. A word that turned up in a meeting where you had to nod along, then again in a document a fortnight later, then again when you had to use it yourself in something you wrote. You did not revise that word once. You own it completely.
What is actually different
Two things and they compound.
The first is repetition you did not have to arrange. A general word has to survive on the strength of one encounter, because nothing in your ordinary week is going to bring it back. A word from your own field comes back on its own. That is the spaced repetition everyone recommends, except you are not maintaining a deck or opening an app. Your job is doing the spacing for you.
The second is that you have somewhere to put it. Memory is not a warehouse of separate facts, it is a web where things hang off other things. A word from your field arrives with a whole scaffold already built: the situations it belongs to, the people who say it, the thing it is subtly different from. A general word arrives with nothing attached and has to build all of that from one definition and one example sentence.
This is why the same person can find general vocabulary hard and pick up forty pieces of jargon in a new job without noticing they did it.
Precision is the actual payoff
There is a version of this that is about sounding clever and I am not really interested in it. The payoff I care about is precision.
Most of the friction in working life is two people using a nearly-right word for slightly different things and not finding out for another fortnight. When you have the exact word you stop needing the paragraph of explanation around it. That is worth something whether you are a nurse, a carpenter or a developer and it is worth quite a lot in writing, where the reader cannot ask you what you meant.
The people I have worked with who write really clearly are almost never the ones with the biggest general vocabulary. They are the ones with the most exact vocabulary for their own domain.
The problem with just reading more
The standard advice is to read more in your field and it is good advice, but it has a hole in it. Reading is where you meet a word, not where you learn it. You skim past nine out of ten unfamiliar words because the sentence still makes sense without them and the tenth one you look up and forget by Thursday for all the reasons in the piece I wrote about looking words up.
What reading gives you is exposure. What it does not give you is the deliberate encounter, at a moment when you have room for it, that turns exposure into something you can produce yourself.
How I built this bit
This is the part of word, daily. I am most pleased with. You can tell it what you do, in your own words and it works out the field you belong to. Then you choose the mix. Every word from your field or one in three or half and half or none at all if you would rather just have the general stream.
I built the mix in deliberately rather than making it all or nothing. All-career gets narrow after a few weeks and stops being a pleasure. All-general is the thing that slides off. Somewhere around a third felt right to me, which is why that is the default, but it is a dial and you can move it whenever you like.
Underneath, everyone who picks the same field and level reads the same word on the same day. That is a technical decision with an editorial consequence I like: your field is a shared stream rather than something generated privately for you, so it stays coherent instead of drifting into whatever the model felt like that morning. There is more on how that works in the build writeup.
Worth trying if you have bounced off vocabulary apps
If you have downloaded a vocabulary app, used it for nine days and quietly stopped, the problem probably was not discipline. General vocabulary asks you to supply all the repetition yourself, forever, for words your life is never going to bring back around. Fighting that with willpower is a losing arrangement.
Pick words your work will hand back to you and the maintenance mostly stops being your job. Start with the field you are actually in rather than the one you would like to be in, because the whole mechanism depends on meeting the word again in the wild. You can always widen it later once the habit is holding.
