Pronunciation: [zˈi͡əɹə͡ʊd] (IPA) 
The word "zeroed" is pronounced as /ˈzɪərəʊd/ in IPA phonetic transcription. It is the past tense of the verb "zero," which means to reduce something to zero or nullify it completely. The spelling of "zeroed" includes the use of "e" after "r" to indicate that the final syllable should be pronounced as "əʊd" instead of "əd." This is because the "e" at the end of the word helps lengthen the sound of the vowel before it.
The term "zeroed" is an adjective used to describe an action or process of setting, aligning, or adjusting something to a zero value or point. It signifies the act of calibrating an instrument, system, or device to a starting or reference point, usually represented by the numerical value of zero.
In the context of measurement or instrumentation, "zeroed" indicates the act of resetting or initializing a device to ensure accurate readings or proper functioning. This process involves adjusting the instrument's internal settings or controls, typically to eliminate any systematic error or offset that might affect measurements or calculations. By zeroing an instrument, one establishes a baseline reference point, from which subsequent values or measurements can be evaluated or recorded accurately.
"Zeroed" can also be used metaphorically to describe a state of complete elimination or eradication. In this sense, it implies the removal or reduction of something to absolute minimum or insignificance. For example, one may say that they have "zeroed" their expenses, meaning that they have reduced them to the lowest possible level.
Overall, the term "zeroed" refers to the actions or states involved in setting to zero, aligning, or adjusting to a starting point, either in terms of measurements or values, or as a metaphorical representation of complete elimination or reduction.
The verb "zeroed" comes from the noun "zero", which is derived from the Italian word "zero" and ultimately from the Arabic word "sifr" meaning "empty" or "nothing". In the Arabic numeral system, "sifr" referred to the concept of "zero". The term was later adopted by various European languages and eventually entered English in the early 17th century. The verb "zeroed" is formed by adding the suffix "-ed" to "zero", indicating the action of setting to zero or reducing to nothing.
