Building Blocks of Esperanto
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Following is a list of Esperanto building blocks. Along with a
list of word stems, it should help to interpret and construct
Esperanto words. I should note that some of the prefixes and
suffixes quoted here are rather loose in their definition and may
also appear in word stems on occasion without the cited meaning.
Where an affix is actually a word stem itself I have attempted to
list that word stem underneath.
I might also add, that this summary is not intended to teach
Esperanto, but to serve as a useful reference for those of us who
are learning. Many things are left unsaid.
Grammatical Endings
~~~~~~~~~~~~~~~~~~~
One of these grammatical endings should appear on the end of most
words, and defines that words role in a sentence. Other suffixes
and prefixes may precede this final identifier.
-o noun amo "love"
-a adjective ama "loving"
-e adverb ame "lovingly"
-n direct object of a verb amon "love"
-j plural amoj "loves"
-jn plural of the direct object amojn "loves"
-i verb, infinitive ami "to love"
-u verb, imperative amu "love!"
-is verb, past tense amis "loved"
-as verb, present tense amas "loves"
-os verb, future tense amos "will love"
-us verb, conditional amus "would love"
Prefixes
~~~~~~~~
All the prefixes precede the stem of the word, many are in fact
word stems themselves. Many may be compounded with other prefixes
and suffixes. Many are rather flexible in their definition.

Participles
~~~~~~~~~~~
This is a very brief summary. The participles can form compound
verbs when they follow the helper "esti" (where they take the ad-
jectival suffix), or they can take adjectival, adverbial or noun
forms on their own (with the appropriate grammatical ending).
PASSIVE ACTIVE
PAST -it- -int-
PRESENT -at- -ant-
FUTURE -ot- -ont-
CONDITIONAL -ut- -unt-
Pronouns
~~~~~~~~
A complete list of pronouns. As in English, the plural "you" is
identical to the singular and does not take the plural suffix.
Possesives take the adjectival form by adding the -a suffix.
mi I
vi you
li he
ŝi she
ĝi it
ni we
ili they
oni one
ci thou (archaic)
si reflexive - refers back to subject
ri he or she (genderless, neoligism)
Correlatives
~~~~~~~~~~~~
Any combination of the prefix and suffix will form a small word
describing something. Remember that movement towards a place is
indicated by using the accusative (-n) suffix.
-o thing
-u person
indefined (some-) i- -a kind
demonstrative (that-) ti- -es posession
interrogtaive (what-) ki- -e place
collective (every-) ĉi- -am time
negative (no-) neni- -om quantity
-al reason
-el way, manner
Numbers
~~~~~~~
Numbers follow a consistent pattern, best illustrated by example.
nulo zero dek unu eleven
unu one dek du twelve
du two dek tri thirteen
tri three dudek tri twenty three
kvar four kvindek ok fifty eight
kvin five cent sesdek a hundred and sixty
ses six sepcent okdek seven hundred and eighty
sep seven dekmiliono ten million
ok eight
naŭ nine
dek ten
cent hundred
mil thousand
miliono million
miliardo billion (thousand million)
Prepositions, Conjunctions and other words with no grammatical ending
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Short words which do not have any grammatical ending are used
very often. They are prepositions, conjunctions, interjections
and even adverbs, and a real pain to always be looking up in a
dictionary. Here is a fairly complete list of all you will likely
meet.
