In current parlance, we also know of "BOOB" and "BUBO" which point to terms like "BLOOM" and "BLOUSE" which are terms explored in another overview.

From  PEST and PESTer we get to ePISTle, often used by churches to PESTer their flocks of faithful MORTals to "get ready".

Pestle and Mortar, in a manner of speaking, imply a rod or projectile and a receptacle which in combination help to "strike" or blow (stroke), "pelt", "crush" or "grind" to pulverize or mash matter and enemy soldiers and civilians. A gentler sense is conveyed by the description of some flowers with a "pestle" or "pistle" or gynecim (in Latin pistillus for pestle). The above terms evolved toward PILL and PILLar, explored in another overview.

Pharmacists use a pestle and mortar to make powders for pills; cooks to make paste like PESTO and masons to make MORTAR to build MAUSOLEUms for mortals as did the widow of MAUSOLEus, a work of such beauty that it was considered one of the seven wonders of the world.

A military mortar or Howitzer or in Spanish "Obus".

Military establishments use the word MORTar to describe a weapon that inflicts high MORTality. Ancient MORTars were catapults that shot pellet or pill like balls. Another vista of MORTar emerges from MORTgages, MORTal instruments of bankers who seek to make profits inspite of MORTality. Another source of MORTality stems from pharmacists, who may err when preparing PILLS with a PESTle and MORTar, causing some patients to feel PESTered and others to end up in a MORTuary.
