I would like to seek your advice on the following phrases:
1) There are masses and masses of clouds in the sky.
- Is that meant many groups of clouds such as cumulonimbus, sirrus, cumulus and so on? It means the sky is filled with clouds, which may be any of these types of cloud.
- 'cloud' is singular. Is 'masses of cloud' more suitable. (such as food and foods have diffrerent meanings?) No, because generally the clouds are discrete objects, unless there is a mass low cloud which has brought rain.
2) I saw masses and masses of food are was/being wasted.
- '...are wasted' refers to piles of food (more than one pile), is it correct? It means total quantity rather than a single pile.
3) There are many 'types of flowers' or 'types of flower'.
- Is there any difference in the meanings of which? The former is specific [there are different species of plants]; the latter is general [flower as term of reference].
