The pronunciation is reminiscent of Spanish or Italian. There are only five vowel sounds, each represented by only one letter and the sounds correspond to the vowels of Spanish and Italian. However there are no exceptions to the rules so they are easily learned. The consonant sounds are familiar to most westerners, though the letters representing them may be slightly different. Esperanto parts of speech are easy to identify instantly because they end in a designated letter.
Word order is simple and is the same as in English.
Prefixes and Suffixes can be added on to virtually any word, even verbs, to create new meanings. Learners sometimes complain that the words are not as close to English as they could be, but you have to realize Esperanto is an attempt at a compromise, not a panacea. In Esperanto, each letter represents only one sound, and each sound is represented only by one letter. The next to last syllable of each word is always stressed, and every word is spelled and pronounced exactly as it looks. Esperantists claim that their language is four times easier to learn than other languages, and I tend to agree, though individuals do vary in their learning speeds.
