Not everyone has one at the moment but in a few years we will.

The use of adult as a verb meaning ‘to behave in an adult fashion, in particular by shouldering responsibilities even when they are unpleasant,’ is a bit of a running joke. There are T-shirts saying ‘Not going to adult today’ which are evidence of the popularity of the idea.

There is increasing evidence of the use of adult in this way.

This is a trojan asteroid which shares an orbit around the Sun with the Earth. The story begins, however, with Jupiter which was discovered to have a large number of these asteroids in its orbit.

ZG: 5

A term from astronomy which arouses a frisson of alarm as we contemplate the fact that we are sharing an orbit with a large lump of rock.

This is the name for the new industry which is about to deliver us our beef steaks and fish fillets as cell-based products. That is to say, instead of grazing cattle so that they can be killed and cut up into steaks, we just produce steaks in the laboratory from cells obtained from the cattle.

This one will matter a great deal more to us in the future.

What the world is now calling the Son of Omicron, the WHO is calling an Omicron subvariant. It is not yet considered to be a variant of interest, let alone of concern, but we are all so sensitive to the idea that another variant will come and we will go back to square one that it has attracted at least media attention.

ZG: 7

This one has caused a minor ripple but since mostly we don’t know whether we have Omicron or Son or Omicron it has ceased to matter.

Unwanted negative thoughts haunt us all but now there is a new technique for stopping them. The thing to do is to use a device such as saying ‘Stop!’ out loud, or snapping your fingers or pulling on an elastic band around your wrist to interrupt the bad thought.

A well-known example of this is the Seinfeld episode which plays with the idea of expressed and repressed emotions, in which George’s father, Frank Costanza, uses the phrase Serenity Now! as his thought stopper to prevent him going into a rage.

This baby is special because the mother has previously experienced a miscarriage, stillbirth or neonatal death. The baby that follows these sad events is like the rainbow after the storm and considered, even more than most babies, to be a symbol of hope.

In this period of home treatments and anxiety about COVID we may all be obtaining one.

This natty is short for natural and relates to the natural bodybuilding movement which eschews all performance-enhancing drugs, such as anabolic steroids, insulin and human growth hormones. Rather a natural bodybuilder will rely on diet and training to produce natural anabolic hormones that increase strength and promote recovery.

ZG: 3

A bit of bodybuilding jargon, important because it relates to the argument about the use of drugs in sport, but not much known to people outside that world.

HEPA is an acronym standing for High-Efficiency Particulate Air (or Absorbance) (or Arrestance) and pronounced [hep-pa]. A filter designated as HEPA has increased efficiency in removing particles produced by dust, pollen, moisture, bacteria and viruses from the air you breathe.

A bit of technical term this one and likely to be forgotten as we relax all restrictions and cease to be concerned about the air we breathe.

A COVID chaser is a person who decides that, if we are all going to catch the virus anyway, they might as well have it at a time that is convenient to them.

This is a bit of politics jargon that we have picked up from the UK. The story goes that the Editor of the Sun, Kelvin McKenzie, regarded it as a duty of journalists to stick a ferret up the legs of politicians. All he meant by this was that they should make life uncomfortable for them.

The back story on this one is a bit complicated but, nevertheless, we appear to be warming to it. Perhaps we are sick of backflip.

The world is constantly on the watch for new variants of COVID-19. This one was identified late last year by researchers at the IHU Mediterranee Infection Institute in Marseilles.

ZG: 4

Worth mentioning because we are so nervous about new variants but dismissed as being of no great interest as yet.

ZG: 3

The word achieved high frequency but for a short period of time.

The figurative use of gear change seems to have come in comparatively recently. It has been popular in horse racing reporting. Queen Elizabeth was reported to be accepting a gear change, from high to low, after her recent illness. And now it has been added to the ScoMo verbal display.

Politicians use figurative terms to put spin on their message. The gear change conjures up power, control and forward movement.
