BOOST/buːst/

To boost something is to increase or improve it: boost confidence; boost sales; a boost to the economy. Increase is more neutral; improve can be quality without a bigger number. Boost as a noun: give something a boost. Do not use boost for a tiny everyday change — it suggests a useful lift. Boosters in medicine (a booster jab) is a related extra use.
