* Stop consonants: These are consonants produced by completely stopping airflow from the mouth. Examples include /p/, /t/, /k/, /b/, /d/, and /g/. They are often called "stops" for short.
* Plosive consonants: This is another term for stop consonants.
* Fortis consonants: This term refers to consonants that are produced with more force or effort, often with greater aspiration (a puff of air). In English, the voiceless stops /p/, /t/, /k/ are often considered fortis, while the voiced stops /b/, /d/, /g/ are considered lenis (less forceful).
Without more context, it's difficult to say for sure what you mean by "solid consonants." If you can provide more information, I may be able to assist you further.
