Noun Phrases : Typical difficulties for learners

Here's a question for you in relation to this week's topic of nouns and noun phrases. Which of the following difficulties are most relevant to the context that you teach in? How serious are the difficulties and how can you help learners to overcome them?

1. Choosing the wrong word endings when attempting to form nouns from adjectives (e.g. *angriness, *youngtime).
2. Not using capital letters appropriately ( e.g. *I speak French).
3. Using countable nouns when the context is uncountable (e.g. *an information, *a good weather, * the news are good).
4. Using plural nouns as though they are singular (e.g. *The people is kind).
5. Making regular plural forms of irregular nouns (e.g. *a lot of womans, *three childrens).
6. Using plural forms of modifying nouns (e.g. * some pencils sharpeners, *a 16 years old girl).
7. Subject-verb agreement with modified nouns (e.g. * Successful users of the language is able to….).
