Igbo Speech and Language Development: Difference or Disorder?

 Igbo Speech and Language Development There is a growing need in the United States for speech-language pathologists to find information on Igbo speech language development.  Here are some of the highlights of Igbo.

Igbo is the principal language of the Igbo people living in southeastern Nigeria. There are approximately 24 million speakers of Igbo.  It is written in the Latin script, which was introduced by British colonialists, and there are over 20 Igbo dialects.

Igbo Facts

  • Igbo Speech and Language Development There are approximately 220,000 Igbo speakers in the United States.
  • Some of the largest populations of Igbo speakers in the U.S. reside in Virginia, Missouri, California, and New Jersey.
  • Cities with large Igbo populations include New York, Philadelphia, Newark, Los Angeles, Boston, Miami, Chicago, and Houston.
  • Igbo is the fourth most spoken language in Africa.
  • Igbo is spoken by approximately 20 million people in Nigeria.

The Sound Systems of Igbo and English

If you’ve read our book, Difference or Disorder:  Understanding Speech and Language Development in Children from Culturally and Linguistically Diverse Backgrounds, then you Igbo Speech and Language Developmentalready know that we need to understand the similarities and differences between the sounds of languages before we can make a decision about whether a speech error is a language influence error or whether it might indicate a speech impairment.  So, take a look at the Venn diagrams below for information about the consonants and the vowels in Igbo and English.

Assume we are testing a child from an Igbo background who is learning English as a second language.

If errors occur on the sounds that are unique to English, that is indicative of language influence. 

If errors occur on the sounds unique to Igbo or the sounds shared between Igbo and English, that is indicative of a speech impairment.  

It’s more complex than that, obviously, but that’s a good place to start.  Then we need to think about the order of acquisition of the sounds in development, and of course the phonotactic constraints.  For more information on all of that, check out the Difference or Disorder book.

Phonological Patterns in Igbo


Patterns of Native Language Influence:Example/description of possible errors:
Allowable syllable patterns in Igbo are vowel (V), consonant-vowel (CV), and syllabic nasal (N)Syllables might be reduced in multisyllabic words
Aside from the syllabic nasal, consonants cannot occur at the end of wordsFinal consonants might be omitted
There are no consonant clustersConsonant clusters might be reduced or a neutral vowel might be added between consonants (e.g. pay for play or puhlay for play)
Substitution of [θ] with [s], [t], [f]thin – sin, tin, fin
There are only four vowel sounds (a, i, u, o)Other vowels might be substituted with [a, i, o, u]

CONTRASTIVE ANALYSIS FOR LANGUAGE: Igbo and English


FeatureIgboEnglishExamples of Errors
Word OrderUsually subject-verb-objectUsually subject-verb objectNone expected
PronounsIgbo does not distinguish between subject and object pronouns (e.g. he vs. him) but person (first, second, and third singular and plural subjects) is distinguished. Pronouns can also be marked for possession.

Subject pronouns: he/she/they/we

Object pronouns: him/her/them/us

She mom is

here.*/ Her mom is here.

Them go to school.*/They go to school.

ArticlesNo articlesHas definite (the) and indefinite (a, an) articlesI have cat.*/I have a cat.
AdjectivesAdjective can precede or follow the noun. There are few adjectives in Igbo. Instead verb suffixes are used to describe actions.Adjective precedes nounI want the cat brown.*/ I want the brown cat.
PluralityMarked with a prefix /otutu/ so cup /iko/ becomes /otutuiko/Add an /s/ to the nounPlurals might not be marked at aIl or might be marked incorrectly. I want two sandwich.*/I want two sandwiches.
Verb conjugationsVerbs do differentiate between present and past. Instead, suffixes are added to the verb to describe the tense and quality of the verb. Examples include: tara/-tere: action in the past (he did); -la/-le: completed action (he has done); -ri: past completed action (he did); -go:  already completed the action (have done); -lu:  to indicate an intensification of the action of the verbVerb conjugates to demonstrate tense changes (I eat, I ate)

Igbo suffixes might be used to mark tense or intensity. (e.g. walklu to express intense walking)

PrepositionsThere is one preposition (na) in Igbo, which has to be understood by contextMany different prepositionsIncorrect use of prepositions

    Hello Ellen,

    I see that approximates such as “l”, “w” and “r” are not listed in the venn diagram and was wondering if they occur in Igbo.

    Thank you for all of the amazing information!

      /l/ and /w/ exist in Igbo. The r of Igbo is a post-Alveolar flap, unlike the English r.

        Just to ensure I am understanding correctly… the /r/ and vocalic /r/ do not exist in Igbo, correct? When treating articulation in a child who is highly influenced by Igbo spoken in the home, we would not consider incorrect production of /r/ and vocalic /r/ an error, since these phonemes do not exist in Igbo. Is this correct?

    Are /sh/ and /ch/ present in Igbo?

    • April 24, 2018 at 8:48 pm #

      Yes, both /ch/ and /sh/ exist in Igbo.

  6. April 24, 2018 at 6:39 pm #

    Do /m/, /n/ and /ng/ exist in Igbo?

    • April 24, 2018 at 8:49 pm #

      Yes, all three of those sounds exist in Igbo too.
