When learning a new language, students will inevitably make mistakes that can be categorized as slips, errors, or attempts. Slips are mistakes that can be self-corrected, errors require explanation as students cannot fix them themselves, and attempts happen when a student tries to say something without fully knowing how. Mistakes may occur due to not fully grasping new information, false friends between languages, or developmental errors as a student's language knowledge progresses and they make logical assumptions about grammar or vocabulary that turn out to be incorrect.

1. Mistakes, Slips, errors and
attempts

2. When students are acquiring a new language is
normal that they make mistakes but we can
divide mistakes into three categories.

3. Slips
• Are mistakes wich students can correct
themselves once the mistakes has been
pointed out to them.

4. Errors
• Are mistakes which students can not correct
themselves and which, therefore need
explanation.

5. Attempts
• Are mistakes that students make when they
try to say something but don't yet know how
to say it.

6. Reasons
• One reason is that students have not quite
grasped the new information and so continue
to make errors.

7. False friends
• Words that sounds the same but have
completely different meaning tis can also
cause trouble, especially for speakers of
Romance language which share a common
heritage with English
• Example: Libreria means book shop not library.

8. Developmental Errors
• These occur naturally as the students language
knowledge develops and are the result of the
students making apparently sensible
assumptions about the way language work.
• example saying I seed instead of I saw.
