Examples

By Part of Speech

adjective

British English

  • The Lyrids shower is a highlight for astronomers.

Examples

By CEFR Level

A2

B1
  • The Lyrids are a meteor shower you can see every year.
  • To see the Lyrids best, find a dark place.
B2
  • The annual Lyrids meteor shower is predicted to peak on the 22nd of April.
  • Astronomers advise watching the Lyrids after midnight for the highest meteor rates.
C1
  • The Lyrids, originating from debris shed by Comet Thatcher, typically produce about 10-20 meteors per hour at their peak.
  • Observational data on the Lyrids' zenithal hourly rate helps refine models of the comet's historical dust dispersion.

Learning

Memory Aids

Mnemonic

Link LYRA (the constellation) + IDS (like in 'meteorids' or 'asteroids'), so 'Lyrids' are the meteors from Lyra.

Conceptual Metaphor

CELESTIAL FIREWORKS (a natural, predictable light display).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Не переводить как 'лириды' или 'лирические'. Это собственное название метеорного потока, связанного с созвездием Лиры.
  • Избегать ассоциаций со словом 'лирика' (poetry).

Common Mistakes

  • Using singular 'Lyrid' (rare).
  • Mispronouncing as /ˈlɪraɪdz/.
  • Confusing with other meteor showers like the Perseids.

FAQ

Frequently Asked Questions

The Lyrids are active annually from about April 16th to 25th, with peak activity typically around April 22nd.

They are caused by Earth passing through the debris trail left by Comet C/1861 G1 (Thatcher).

They are a medium-strength shower, usually producing 10-20 meteors per hour at peak under ideal dark-sky conditions, though rare outbursts have occurred.

In British English, it's typically /ˈlɪrɪdz/ (LI-rrids). In American English, it's commonly /ˈlaɪrɪdz/ (LYE-rids), reflecting the pronunciation of the constellation Lyra (/ˈlaɪrə/).
