This document discusses morphological challenges for Thai students learning English. It explains that morphology is the study of word structure, and words are made up of morphemes - the smallest units that can carry meaning. There are two types of morphemes: free morphemes that can stand alone as words, and bound morphemes that cannot stand alone and include suffixes like "-s". The document analyzes specific parts of speech like adjectives and adverbs that are used differently in English and Thai. It also notes challenges with inflectional and derivational bound morphemes, as Thai does not have these. Finally, it lists several English grammatical morphemes that studies have found difficult for second language learners, such

2. Morphology is a study of word
structure.
A word is made of morphemes which
are
smaller units that can carry meaning.
For example;
work+er = worker
bone+s = bones

3. There are two kinds of morphemes
 Free morpheme can stand by itself as
a single word.
 Bound morphemes normally cannot
stand alone, for example, plural
morpheme –s.

4. Based on our teaching experiences,
types of morphology that pose
difficulties for Thai students
Free morpheme
 Lexical morpheme
Nouns do not pose any difficulty.

5. Adjectives do pose difficulty on it uses
because when the adjective is used, it
is put
In front of a noun that it modifies which
is
different form Thai that adjective
normally
comes after a noun.
For example: English : It is a big black
dog.

6. Adverb does also pose difficulty for Thai
learners as well in term of it uses.
For example:
English : He walks slowly. / He slowly
walks. (Some adverb can be put after
verb or before verb.)
Thai : In Thai, adverb
need to be put before verb. )

7. Functional morpheme
Conjunction, preposition, and pronouns
do not
post difficulty because many of them
share
the uses in common. Even there are
some
uses that does not actually use in the
same
way, but still learners keep on
practicing
and finally acquire word i.e. on—use
as in

8. Suggestion:
Solved by keep students practicing often
and
provide context when practice.

9. Bound morpheme
Both inflectional and derivational pose
difficulty for Thai learners because both
inflectional and derivational morpheme
are
not parts of Thai language which is their
mother tongue.

10. Johanne Paradis (2005) found out that
grammatical morphology in children
learning English as a second language
that pose difficulties to learner are
following:
 third person singular –s/-es
 past tense –ed
 irregular past tense
 verb to be as auxiliary verb
 do as auxiliary verb
 plural –s
 progressive – ing
