Agreement (also concord) is a grammatical phenomenon in which two or more words in a sentence must match in specific features — such as person, number, gender, or case — determined by their grammatical relationship. In English, the subject and verb must agree in number and person: the dog barks (3rd person singular) vs. the dogs bark (3rd person plural). Agreement is a pervasive feature of many of the world’s languages and one of the more persistent challenges for L2 learners.
In-Depth Explanation
Types of agreement
Different languages require agreement across different feature sets:
| Feature | Example language | Example |
|---|---|---|
| Number (singular/plural) | English, most European languages | she goes / they go |
| Person (1st/2nd/3rd) | Spanish, Italian, Arabic | hablo (I speak) / habla (s/he speaks) |
| Gender | French, Spanish, Arabic, Russian | un livre rouge (masc.) / une robe rouge (fem.) |
| Case | Russian, Latin, Finnish, Japanese (particles) | nominative vs. accusative endings on nouns and adjectives |
| Definiteness | Arabic, some Semitic languages | adjective takes definite prefix when noun is definite |
Agreement in English vs. Japanese
English has simplified agreement (number + person on verbs; number + possessive on nouns). Japanese has fundamentally different agreement requirements:
- No grammatical gender agreement in Japanese
- No number agreement on verbs (no marking for singular vs. plural subject on the verb)
- Politeness/register agreement: verb endings must match the formality level of the speech context — 食べる (plain) vs. 食べます (polite) — a form of agreement between speaker, hearer, and pragmatic context
- Particle system: while not “agreement” in the inflectional sense, Japanese particles track semantic role relationships (ga/wo/ni/de/to) that cross-linguistically correspond to case agreement
Agreement in SLA and acquisition order
Subject-verb agreement is notoriously difficult for adult L2 learners. In morpheme acquisition order research (Dulay & Burt 1974), the third-person singular -s in English (she walks) is consistently among the last morphemes acquired — even by highly proficient L2 speakers. This is particularly striking because it carries minimal information load (number is already marked on the subject noun) and is frequented in the input.
Possible reasons for late acquisition:
- Low informational value (redundant with plural marking on the noun)
- Low perceptual salience (brief, unstressed suffix)
- L1 transfer: many L1s lack subject-verb agreement, so the form has no cross-linguistic support
History
Grammatical agreement has been described since antiquity — Latin grammarians systematically analyzed noun-adjective concord. In modern linguistics, agreement received formal treatment in Chomsky’s Standard Theory (1965) through phrase structure rules and later in Government and Binding (1981) via INFL and agreement projections. AgrP (agreement phrase) was a major node in Minimalist-era syntax before being largely abandoned in favor of Agree operations on functional heads. Typological research (Corbett 1991) provided a comprehensive cross-linguistic taxonomy of agreement systems. In SLA, Lardiere’s (1998, 2007) “morphological mapping” work on advanced L2 English speakers who persistently omit 3rd-sg -s sparked debate about whether agreement features are acquired but not mapped, or not acquired at all.
Common Misconceptions
- “Agreement is just about verbs.” Agreement operates across multiple word classes — adjectives agree with nouns in French, Spanish, and many other languages; determiners/articles agree with nouns in gender and number; pronouns agree with their antecedents.
- “Japanese has no agreement.” While Japanese lacks the noun-gender and subject-verb number agreement of European languages, it has register-sensitivity built into verb endings and auxiliary choice — a pragmatic-grammatical agreement system.
- “Once you know the rule, you’ll stop making agreement errors.” Agreement errors persist in L2 speech even at advanced levels — especially under production pressure (fast speech) or in low-frequency constructions. Knowing a rule doesn’t guarantee its real-time application.
Social Media Sentiment
L2 English learners frequently discuss agreement errors — particularly the persistent 3rd-sg -s problem. Many advanced English speakers from Japanese, Chinese, or Korean L1 backgrounds note they still occasionally omit verb agreement suffixes in spontaneous speech even after years of study. This is treated as one of the clearest examples of a form that is low-value communicatively (rarely causes misunderstanding) but high-value grammatically (marks native-like fluency).

Practical Application
- 3rd-sg -s in English: If English is one of your languages and you’re a Japanese L1 speaker, pay special attention to the 3rd-singular -s — it is the last morpheme acquired and the most commonly omitted by proficient speakers. Explicit monitoring during writing practice helps build the habit.
- Gender agreement in European languages: When reading French or Spanish parallel texts with Japanese translations (common in grammar study), pay attention to how article and adjective endings shift with noun gender — a category entirely absent in Japanese.
- Japanese keigo register agreement: Japanese politeness levels require consistent agreement throughout a conversation’s formality register — mixing plain and polite forms is a pragmatic agreement violation.
