Morpheme & Medial Suggestions

Input:  "ကျောင်ငသား"  (typo in first morpheme)
Split:  ["ကျောင်င", "သား"]
         ^^^^^^^^^ invalid

Step 1: SymSpell corrects "ကျောင်င" → "ကျောင်း"
Step 2: Reconstruct: "ကျောင်း" + "သား" → "ကျောင်းသား" (student)

from myspellchecker.core import SpellCheckerBuilder

checker = (
    SpellCheckerBuilder()
    .with_compound_resolver(True)
    .build()
)

# Typo in compound word — morpheme strategy finds the correction
result = checker.check("ကျောင်ငသား")
# Suggests: ကျောင်းသား

medial_swap_pairs:
  - ["ကျောင်း", "ကြောင်း"]   # school ↔ cat/reason
  - ["ကျွန်", "ကြွန်"]         # servant ↔ (confusion)

from myspellchecker.core import SpellCheckerBuilder

checker = (

    .build()
)

# Ya-pin/ya-yit confusion — medial swap strategy generates the correction
result = checker.check("ကြောင်းသွားတယ်")
# May suggest: ကျောင်းသွားတယ် (depending on context)
