Better understanding of English
The patterns in Esperanto were designed to be easy to see and to use.
Esperanto: tenis, tenas, tenos/ kaptis, kaptas, kaptos/ falis, falas, falos
General Concept: past, present, future
English: held, hold(s), will hold caught, catch(es), will catch fell, fall(s), will fall
Esperanto encourages the habit of looking for patterns because of its extensive system of prefixes and suffixes, which can be utilized freely and with confidence because there are no exceptions to their applicability.
Since most of the prefixes, suffixes and root words used in Esperanto are derived from Latin or other European languages, there is a high level of transferable learning involved in Esperanto use.
Esperanto is useful for strengthening awareness of grammatical parts of speech as nouns end in -o, adjectives in -a, adverbs in -e and verbs in -as, -is, -os, -u, or -us, depending on tense and mood.
