Do nothing.

Examples

iex> Stemmer.Step1a.leave_us_ss("abyss")
{:found, "abyss"}

Delete if the preceding word part contains a vowel not immediately before the s (so gas and this retain the s, gaps and kiwis lose it).

Examples

iex> Stemmer.Step1a.remove_s("gas")
{:next, "gas"}

iex> Stemmer.Step1a.remove_s("this")
{:next, "this"}

iex> Stemmer.Step1a.remove_s("gaps")
{:found, "gap"}

iex> Stemmer.Step1a.remove_s("kiwis")
{:found, "kiwi"}

Replace by i if preceded by more than one letter, otherwise by ie (so ties → tie, cries → cri).

Examples

iex> Stemmer.Step1a.replace_ied_ies("tied")
{:found, "tie"}

iex> Stemmer.Step1a.replace_ied_ies("ties")
{:found, "tie"}

iex> Stemmer.Step1a.replace_ied_ies("cries")
{:found, "cri"}

Replace by ss.

Examples

iex> Stemmer.Step1a.replace_sses("actresses")
{:found, "actress"}

## Examples

iex> Stemmer.Step1a.replace_suffix("abyss")
"abyss"
