When a learner's second language learning system seems to freeze or get stuck at some more or less deviant stage, that phenomenon is known as

Correct option is B

Fossilization is a phenomenon in second language acquisition (SLA) where a learner's errors become habitual and difficult to correct. It can occur at any level of language, from phonology to grammar to semantics.

There are a number of factors that can contribute to fossilization, including:
 Lack of exposure to the correct form of the language
 Lack of feedback on errors
 Anxiety or fear of making mistakes
 Cognitive factors, such as processing speed or working memory capacity

Fossilization can be a frustrating experience for learners, but it is important to remember that it is a normal part of the SLA process. There are a number of things that learners can do to try to overcome fossilization, such as:
 Seeking out feedback on their errors
 Practicing the correct form of the language in a variety of contexts
 Using strategies to reduce anxiety or fear of making mistakes
 Working with a language teacher or tutor

Fossilization is a complex phenomenon, and there is still much that we don't know about it. However, by understanding what fossilization is and how it can occur, learners can take steps to try to overcome it.

Fossilization can be difficult to overcome, but it is possible with time and effort. By seeking out feedback on their errors, practicing the correct form of the language, and using strategies to reduce anxiety or fear of making mistakes, learners can make progress in overcoming fossilization.

In second language acquisition (SLA), fossilization refers to the phenomenon where a learner’s language development stops progressing, and certain errors or non-standard forms become a permanent feature of their speech or writing. Even with exposure to correct forms, these “frozen” structures persist.

Information Booster:​
Term Origin: Introduced by Larry Selinker in 1972 as part of Interlanguage Theory.

Causes: Limited motivation, lack of corrective feedback, reduced exposure to native-like input, or satisfaction with a functional proficiency level.

Example: An advanced English learner consistently says “He go to work every day” instead of “He goes to work every day”, and never corrects it over years.

Additional Knowledge:
Freezer:  Not an SLA term — possibly a distractor mimicking “fossilization.”

Language Learning Blockade: Not a formal linguistic concept; could loosely refer to temporary learning difficulty, but not the established term.

Language Scaffolding:  Refers to the support given by teachers/peers to help learners progress — the opposite of fossilization.
