security
/sɪˈkjɔːɹəti/
When referring to the feeling of being safe or the precautions taken to protect something, 'security' is usually an uncountable noun (you don't say 'securities' for a feeling of safety). In financial contexts, however, 'security' becomes a countable noun. In this case, you can use the plural form 'securities' to refer to stocks, bonds, or other tradable financial assets. Be careful not to confuse 'security' (the state of being safe) with 'safety' (the condition of being protected from accidental harm). For example, a seatbelt provides safety, while a lock on a door provides security.
