• According to Garner's Modern English Usage, continually and continuously mean different things. Continually means that something happens regularly but in discrete bursts ("The municipality continually issued boil-water advisories at a rate of almost once a month"), while continuously means that something is happening at a constant and uninterrupted rate ("The lava has continuously erupted from the volcano for a week; it has not stopped erupting even for one second").
• Garner offers this mnemonic: imagine that the -ous of continuous stands for "ne ninterrupted equence".

• (in regular or repeated succession): time and again, little by little, momently, at every turn; see also Thesaurus:gradually or Thesaurus:sequentially
• (in a continuous manner): ceaselessly, incessantly, nonstop; see also Thesaurus:continuously
