organism living on a host
A small animal or plant that lives on or inside another living thing and takes food from it, usually hurting it.
Schema d'uso:
a parasite on [an animal / a plant / a person]
Errore comune:
Learners sometimes use 'parasite' to refer to any germ or microbe. In biology, a parasite is specifically an organism that lives on or in a host and gets nutrients from it, while terms like 'bacteria' or 'virus' refer to different kinds of microorganisms, not all of which are parasites.
Sinonimi
organism (More general; refers to any living thing, not only those that live on a host.)
|
pathogen (A disease-causing agent; overlaps when the parasite makes the host sick, but not all parasites are pathogens.)
Contrari
host (The organism that supports and is used by the parasite, the opposite role in the relationship.)

person living off others unfairly
Someone who lives from other people’s money or help and does not give anything back, in a way people think is wrong or selfish.
Schema d'uso:
[someone] is a parasite on [someone/something]
Errore comune:
Learners sometimes use 'parasite' for any lazy person. In this sense it is usually stronger and more insulting, suggesting someone lives off others over a long time and is seen as morally wrong, not just occasionally lazy.
Sinonimi
freeloader (Informal; focuses on someone who always lets others pay or do the work.)
|
sponger (Informal, especially British; suggests someone who regularly borrows or takes money or support.)
|
leech (Strongly negative; emphasizes that the person drains others emotionally or financially.)
Contrari
contributor (Positive; describes someone who gives effort, money, or help instead of only taking.)

optional but non-core sentence element
In grammar studies, a word or phrase that is not needed for the basic sentence to be correct, but can be added for extra meaning.
Schema d'uso:
a parasite in [this / that] sentence
Errore comune:
Most learners never meet this specialized sense. It should not be used in everyday speech to talk about grammar; common terms like 'extra phrase' or 'adjunct' are usually clearer.
Sinonimi
adjunct (Technical grammar term; more common than 'parasite' in modern descriptions for optional sentence elements.)
Contrari
complement (In grammar, a word or phrase that is required by another word to make the sentence structure complete, the opposite of an optional element.)
