Scientific terminology informal or non-technical English, to say "strictly speaking" for "sensu stricto" and "broadly speaking" and so on is valid. Even in formal writing, there is no formal requirement to use the Latin terms rather than the vernacular. Valid reasons for using these Latin or partly Latin expressions are not points of pretentiousness; they include: A good example is the word "laser", an acronym for "Light Amplification by Stimulated Emission of Radiation", and therefore all its letters should be capitalized. However, because of frequent use, this acronym became a neologism, i.e., it has integrated into English and most other languages. Consequently,
Sound amplification by stimulated emission of radiation the National Academy of Sciences of Ukraine, and Caltech. SASER's central idea is based on sound waves. The set-up needed for the implement of sound amplification by stimulated emission of radiation is similar to an oscillator. An oscillator can produce oscillations without any external feed-mechanism. An example is a common sound amplification system with a microphone, amplifier and speaker. When the microphone is in front of the speaker, we hear an annoying whistle. This whistle is generated without extra contribution from the sound source, and is self-reinforced and self-sufficient while the microphone is somewhere in front of the speaker. This
