    • -ation A suffix forming nouns of action, and often equivalent to the verbal substantive in -ing. It sometimes has the further meanings of state, and that which results from the action. Many of these nouns have verbs in -ate; as, alliterate -ation, narrate -ation ; many are derived through the French; as, alteration, visitation ; and many are formed on verbs ending in the Greek formative -izeFr. -ise); as, civilization, demoralization .

    • n -ation A suffix of Latin origin, occurring in nouns of action, etc. These nouns are properly abstract nouns equivalent to English nouns in -ing, and are taken directly from the Latin, as citation, commendation, creation, education, liberation, etc., and formed in Latin (commendatio, etc.) from the verbs represented in English either by forms without suffix (from the Latin infinitive), as cite, commend, etc., or by forms in -ate (from the Latin perfect participle), as create, educate, liberate; or formed in modern speech, whether from verbs without suffix, as in fixation, quotation, etc., from fix, quote, etc., or from verbs in -ate, as concentration, desiccation, from concentrate, desiccate, etc., or from verbs of non-Latin origin, as starvation, flirtation, these being the earliest formations (in the middle of the eighteenth century) in -ation from verbs of native origin (starve, flirt). Some words in -ation have no accompanying verb in English, as constellation, lunation, negation, etc.

In science:

Our general results include widely studied gravity theories and inflation models as special cases, and show how the well known consistency relation and spectra in ordinary Einstein gravity inflation models are affected by the generalized nature of the gravity theories.
Inflationary spectra in generalized gravity: Unified forms
In weakly coupled scalar field models of inflation, the spectrum of fluctuations is calculated by assuming that fluctuation modes start out in the vacuum (i.e. minimum energy density) state at the beginning of inflation and subsequently evolve as determined by the equations of motion.
Trans-Planckian Physics and the Spectrum of Fluctuations in a Bouncing Universe
Here inflation is entirely based on the kinetic term and it can take place even if the field is running very fast (X is large); typically c2 S ≪ 1 for k-inflation.
Enhancing the tensor-to-scalar ratio in simple inflation
Therefore, in models where c2 S > 1, the energy scale of inflation must be higher than in ordinary slow-roll inflation with canonical kinetic term.
Enhancing the tensor-to-scalar ratio in simple inflation
However, if one looks at models of inflation in these compactifications, a generic problem crops up in the slow roll inflation.
