   • 2025 September 29, Jorge Nogueras, “La plej mallonga tago”, in uea.facila‎^[1], archived from the original on 12 December 2025:

     Nu, plej verŝajne sciencistoj ĉikanus vin, kaj klarigus al vi, ke fakte tagoj daŭras foje iomete pli, foje iomete malpli.

     Well, most likely scientists would argue with you frivolously, and explain to you, that days in fact last sometimes a little more, sometimes a little less.

Only applies to adverbs or adjectives.
For nouns see multo ("many") + "de" or plimulto ("majority") + "de".
Conventionally Esperanto speakers tend to say "many" when meaning "most".
