Almost all subtle shilling tactics in the age of internet involve either pre-emptive or remediatory targeting of keywords with the intent to associate or dissociate certain meanings around it.
Let's use one example, a certain psyop which I prefer not to name talks about a specific number of days of darkness, and, in eschatological literature, we have the concept of the three days of darkness. As we near the cosmic catastrophe and the elites begin to overdrive the informational damage control (algorithm ghettos, autocensorship, etc) it's paramount they keep the true nature of it hidden from the serfs (as the serfs only give them power under the continuation of mind control).
So, by associating a trigger word with something that will be ad nauseam painted as ridiculous and to be dismissed by the [media], they already control the situation with less wasted calories, using the serfs brains' themselves as logical propagators of the desired manufactured understanding.
Syntactical Halos work in the same (but reversed) manner as Implicit Association, since our brains are correlational machines, rather than a hyperlogical ECC device.
Once you pay close attention to this core concept of subtle mind control you'll begin to see how many things have been kept under cognitive locks by nothing more than the fear of ostracism that makes the serfs not look where they are told it is ridiculous to do so...
Remember, stand alone and be free!

Its a way of controlling language. If they can associate the word pandemic with Covid then they only have to say pandemic measures and people think Covid. But when they legally act they include all sorts of 'pandemic' measures.
This then makes it hard to talk about because they have turned the word pandemic into the phrase pandemic. Phrases have context that is carried along where as words are single atomic ideas.
For example. They can use the context of the Covid narrative to pass general purpose laws for anything they call pandemic....but as far as they are saying it is always in the context of Covid. So they will subtly pass the law for all purposes without needing to say it to the people who may balk
