1. Mountains

Geography & Places · Geographic Feature Abbreviations

Plural form used for mountain ranges on maps and in atlases, as in Rocky Mts., Ural Mts. or San Juan Mts.; Mtns. is a common alternative.

Example: Snow is forecast for the San Juan Mts. above 9,000 feet.

Atlases and older textbooks use Mts. to fit crowded map labels. Mts. can also be the plural of Mt. in a list of individual peaks.

2. Master of Theological Studies (MTS)

Education & Academia · Degree Abbreviations

Two-year academic master's in theology or religion offered by divinity schools such as Harvard, Duke, Emory and Vanderbilt. Unlike the MDiv, it is not designed for ordination and often serves as preparation for doctoral study.

Example: She completed an MTS at Harvard Divinity School before beginning a PhD in religious studies.

Written M.T.S. Yale Divinity School offers a comparable degree called the MAR (Master of Arts in Religion). Students in MTS programs may still take ministry courses, but the curriculum centers on research languages, theory and a thesis or capstone.

3. Member of technical staff (MTS)

Business & Finance · Job Title Abbreviations

Engineering job title used by some technology companies and research labs for software engineers and scientists, often chosen to keep hierarchy flat so people are judged by their work rather than rank. Bell Labs, VMware and several AI research companies have used it.

Example: He joined the AI lab as an MTS working on model training infrastructure.

The title traces back to Bell Laboratories, where "member of technical staff" was the standard designation for researchers. Some companies add levels such as senior MTS or principal MTS, while others, including OpenAI, have used the plain title to signal a non-hierarchical engineering culture.
