Pressure

From Latin "pressura", from "premere" (to press). The physical sense — force per unit area — sits alongside the emotional one, “under pressure,” both from the idea of being pressed.

  1. noun · /PRESH-er/

    Force spread over an area — how concentrated a push is, not just how strong.

    Why a sharp knife cuts and a flat hand does not with the same force: the same push over a smaller area means far greater pressure.

    Snowshoes work by lowering pressure: the same body weight spread over a larger area stops you sinking.

    Pressure is force divided by area, so it is distinct from force itself. A woman in stiletto heels exerts less total force than an elephant but far more pressure under each heel.

    Mental or emotional strain arising from demands, expectations, or urgency.

    the felt weight of stress.

    Close kin to anxiety, but tied to an external demand rather than a vague threat.

  3. verb · /PRESH-er/

    To try insistently to coerce or persuade someone.

    leaning on someone until they give way.

    They pressured him into signing.

    Applying force by degrees rather than all at once.
