adj. relating to or serving as a testimonial
The word "testimonial" traces back to Latin testimonium (evidence, witness), derived from testis (witness) + monium (a suffix indicating function or condition). The root testi preserves the idea of witnessing, while moni suggests a reminder or declaration. Over time, it evolved in English to denote formal praise or evidence, reflecting its legal and commendatory dual usage.
