What does auxanometer mean?
An auxanometer is a specialized instrument used to measure the growth of plants, particularly how much a stem or other organ lengthens over time. In use, observations recorded at intervals can document a plant's change in size. The term is chiefly found in botanical, horticultural, and scientific contexts rather than everyday speech. Its unusual name is transparent: it combines the Greek element auxan-, associated with increase or growth, with -meter, a measure or measuring device. Although modern digital imaging and other non-contact methods have provided alternatives for tracking growth, the auxanometer remains a clear example of a purpose-built scientific instrument. It is also useful as precise vocabulary because it names, in one term, an instrument whose entire purpose is to make a slow biological change measurable.
nounAn instrument for measuring the growth of plants, particularly their increase in length over time.
- An instrument used to measure plant growth, especially an increase in length over time.
"Researchers used an auxanometer to record the daily increase in seedling height."
"Researchers used an auxanometer to record the daily increase in seedling height."
"The measurements taken with an auxanometer showed that the seedlings grew more rapidly under warmer conditions."
The plural is formed by adding -s to the singular.
"The laboratory installed auxanometers beside several rows of experimental plants."
The name says exactly what the device does: it measures increase, turning slow plant growth into recorded data.

Where does auxanometer come from?
The word is a scientific formation based on Greek auxanō, meaning “to increase or grow,” and metron, meaning “measure,” reflected in the measuring suffix -meter. It entered English as a specialized name for an instrument used to track plant growth. The same Greek root appears in English words including auxesis, auxetic, and auxin, all associated with growth, increase, or expansion.
How auxanometer is actually used
This is a rare, chiefly botanical and scientific term. In general writing, a plant-growth-measuring device may be described more plainly.
