minimum level that triggers change
The smallest level, amount, or point where something starts to happen or to be noticed.
الگوی کاربرد:
the threshold for [something]
اشتباه رایج:
Learners often use “limit” instead of “threshold” in all situations. “Limit” is very general, but “threshold” usually means the minimum point where something starts to happen or be noticed (for example, “income threshold,” “pain threshold”). Another common mistake is saying “in the threshold for” instead of “the threshold for” or “the threshold of.”
هممعنیها
limit (A very general word for a point that you cannot go past; it does not always suggest a starting point like “threshold” does.)
|
cutoff (Often used in technical or official contexts for a fixed point that separates two groups or states, similar to a threshold used as a dividing line.)
متضادها
ceiling (Refers to a maximum allowed level, which contrasts with “threshold” as a minimum level at which something begins.)

bottom part of a doorway
The piece at the bottom of a door that you step over when you go into or out of a room or building.
الگوی کاربرد:
the threshold of [a room/building]
اشتباه رایج:
Learners sometimes confuse “threshold” with “doorstep.” A threshold is the strip at the bottom of the doorway that you step over; a doorstep is usually the outside step in front of the door. In many everyday situations people may not care about the difference, but in careful descriptions it matters.
هممعنیها
doorstep (Often refers to the step just outside a door, not the actual strip at the bottom of the doorway, but in casual speech they can overlap.)
|
sill (More often used for “windowsill,” but “doorsill” can also refer to the same physical part as a threshold.)
متضادها
interior (Refers to the inner part of a room or building, which contrasts with the entrance boundary marked by the threshold.)

point before a new stage begins
A point in time when you are just about to enter a new and important stage or period.
الگوی کاربرد:
on the threshold of [a new stage]
اشتباه رایج:
Learners sometimes say “in the threshold of a new life” instead of the fixed pattern “on the threshold of a new life.” Another mistake is to use “edge” in formal writing when “threshold” is more natural for positive or neutral new stages (for example, “on the threshold of a new era,” not usually “on the edge of a new era”).
هممعنیها
brink (Suggests being very close to something, often dramatic or dangerous; “threshold” is more neutral and can be positive or negative.)
|
verge (Means to be very close to something happening; “threshold” sounds slightly more formal and often suggests a new stage or era.)
متضادها
end (The final part of a period or process, in contrast to “threshold,” which refers to the beginning of one.)

apply a cutoff to data/signal
In technical fields, to change a signal or data by using a fixed value, so numbers above or below that value are treated in a special way.
الگوی کاربرد:
to threshold [data/signal/image]
اشتباه رایج:
This verb is rare outside technical contexts. Learners may incorrectly use it in general English (e.g., “We thresholded his anger”), which sounds wrong. In everyday English, use verbs like “limit,” “filter,” or “cut” instead.
هممعنیها
clip (In audio, means cutting off parts of a signal above a level; similar idea but more specific to limiting peaks rather than general thresholding.)
متضادها
leave unprocessed (Means not to apply any transformation or cutoff to the data, which contrasts with actively thresholding it.)
