The point in second language acquisition when growth stops and further development is unlikely is known as which?

• A. Fossilization
• B. Interlanguage
• C. Overgeneralization
• D. Interference

Answer: (A)

Fossilization is the moment when growth in a second language stalls and the learner’s linguistic system becomes fixed, making further development unlikely. At this stage, the interlanguage stops reorganizing rules and persistent forms can become entrenched, even with continued exposure and practice. This is different from interlanguage as a whole, which is the ongoing, evolving system of an learner’s language. It also isn’t about applying a rule in the wrong context (that’s overgeneralization) or about errors caused by influence from the first language (that’s interference). For example, if a learner consistently uses a past tense form like “goed” for “went” after many years of study and no noticeable improvement occurs, that entrenched error illustrates fossilization. The idea captures the idea of a plateau in development that may persist without targeted intervention.
